Using Guitar Amp As Speaker For Sale (2024 Update)

I have never offered a product review for any product but I had to make an exception for this one. I am 69 years old, have been playing music for over 50 years, and I have just begun learning the harmonica. This amp is perfect for me for a number of reasons. First of all, it's portable. I can take it anywhere – from my living room – to that picnic table at the park – to my guitar player's front porch. I've had it for a while and I'm still on the batteries that came with it. (You can get an optional power supply for it if you want.) Second – it sounds great and has plenty of volume for personal practice and for use in small settings. With the GAIN and VOLUME controls, you can easily get the response you want. The EQ control only makes a subtle difference in frequency response but nothing dramatic. The DELAY function, however, is very effective and fun to use. Next – a variety of additional input and output jacks make it very flexible. I can plug in my MP3 player and play along with a backing track, for example. It also has a headphone jack, an extension speaker jack, and a DC power jack. Finally – and most importantly – It's fun to use and, because of that, I find myself practicing longer and enjoying it more. I'm new at holding a mic and at first it felt awkward. Now, because the FLY 3W is so much fun to use, holding the mic has become second nature. OK – now you're waiting for the downside. Well, other than the EQ control comments I made earlier, I don't have any. At first, I thought it could benefit from a handle but, upon closer inspection, I discovered the recessed finger grip on the top of the case. (Very clever Blackstar.) This is a well designed portable practice amp. (It even looks aesthetically pleasing.)Bill

First things first; this combo pack DOES include the power supply but batteries are NOT included in the combo pack. Despite the great reviews, don't expect this to sound like a full-size amp; the small speaker mean this amp lacks low end. The pair does sound OK playing in stereo music through the aux input; good detail and sound quality except for the missing bass. As a practice amp, especially through headphones, this thing rocks; with the ISF control you can make it sound like a Fender or a Marshall Amp. Cleans are good but the high gain channel can sound a bit messy if you crank it to 11. The amplifier is more than loud enough for home practice even without doubling the power to 6 watts by adding the second speaker. I don't own a full-size electric amp but I've found out that running the cab-simulated headphone output into my acoustic amp's aux input gives an excellent equivalent so I probably won't bother with a 'real' electric guitar amp; this setup sounds sooo good.Dave W

I was very pleasantly surprised and the range of EQ and the control of compression the Fly 3Bass gives me, not only a great practice amp but mic it up through a PA and it sounds amazing. Great running on batteries (last about 12 hours) or mains. I did a back garden set with couple of friends on acoustic guitars me on electric bass via Fly 3 and it sounded really good so i am very pleased with my purchase. Only thing i had to do was back off tone and bass enhancer on my active bass as it slightly overpowered the amp but i get that on my stage rig as well so expected that.Barry J.

I really like this amp. I bought it used at a really good price, so I was very pleasantly surprised at how nice it sounds. It has loads of power and nice tone. I bought it as a practice amp, but I wouldn't hesitate to use it on stage in a small club.voltyr

THE 8 INCH SPEAKER IS ALITTLE WEAK SOUNDING ,CAB IS BUILT WELL, EFFECT ARE GOD THE ACTIVE EFFECT IS REALLY KOOL SOUNDING,WELL WORTH THE 100 DOLLARS I PAID JUST NEED TOO UPGRADE SPEAKER SIZE TO A 10 INCH!!PAUL

Fantastic amp for the price! The clean channel is great, and has time delay effects that is unexpected for an amp in this range. The overdrive is excellent too, and you can control different frequencies as well. It also has two inputs for guitars, and a microphone input! So you can jam with friends and sing along. At 40w output, it is pretty loud. If you are in the fence, get it! You won't regret it!integrationbyparths1

I bought this amp to have a small, cheap portable amp to play harmonica through. For that, it is decent enough. I use a Shure bullet mic and the amp produces good enough tone and is plenty loud for practice or small gigs. When I plug my tele into it the clean channel is decent and clear, but the overdrive channel is junk and hurts my ears. I would rather run the clean channel and use a fuzz or distortion pedal. So that being said it is decent enough to practice licks on and it is tiny so it tucks away easy. If you look around you can find a bigger amp with more features used for the same price but if you want a new amp, this one is probably worth what they charge for it. I would only buy it if you have a specific purpose for it though.Roy

It's small, and pretty portable. However, the sound quality is trash, given the speaker is tiny, but the overdrive is just horrible. If you buy this, try returning it. If you can't return it, just get a fuzz pedal and leave it on clean. Imo, just buy the mustang lt25-50Hotdog Games

Unbelievable. This is NOT my Vox AC30, and nor is it my 100W Katana. However, for a package that is powered by batteries and can, quite literally, fit into the palm of your hand, the Katana Mini is simply fantastic. The amp models are brilliant and the delay (reverb) function is an excellent feature. On "clean" settings the volume of the amp is perfectly adequate and will fill a room with no issues, and on the "crunch" and "brown" settings, the amp was more than loud enough to fill a large room at 2/3 volume. Whilst I personally think that this is not quite enough for an advanced/intermediate players sole amplifier, I would completely agree that for a beginner, they would need no more than this. Having tried options from Yamaha and other brands, this is firmly my favourite battery powered micro amplifier for any level of guitarist and equipment, the tone is simply that good! The best way I can describe it is this – when I first plugged my PRS McCarty 594 into it, I was vaguely aware that I wasn't playing through my Vox. However, after five minutes or so, I had completely forgotten this wasn't a "real" amp, and had to keep looking down at the tiny box on the floor to believe it! Well done, Boss!Mr I. F.

I use it primarily as a practice amp at lower levels, but I'd feel confident doing coffee house gigs with it, and maybe smaller clubs too. It sounds warm and rich at low volumes, and the EQ is effective. All three voices are useful and I'm not left wanting. I have to make special mention of the delay. I adore reverb (including and especially spring reverb and gritty, trashy reverb of all kinds) but a simple delay circuit is way more useful in this amp. Doubling, slapback, echoes. The treble roll-off and fixed feedback are well-tuned. If you're using this for busking or other guerilla performance, you will suddenly realize that a single delay is worth more than a thousand reflections, because those reflections sound godawful* against naturally-occurring surfaces. *maybe awesome in a sound design way thoughChesterfleet

Bought this for my grandson to use. My other amps are too big for him to take to lessons and school. This isn't the cheapest practice amp but the sound is great and the overdrive DSP is as good as much more expensive amps. Excellent amp for the money.digital_photog

Seems as well built as the other options I've seen. Better tonal range than Vox and better than having to buy 2 or three devices. First impressions were not that good but as I've used it a bit more I can see me getting more used to it. I probably expected to much and was basing my hopes on the FLY amps. I think the effects are too limited to be worthwhile and would prefer Blackstar to focus on better amp tone. Still, I'm happy with it and for the type of device this is I know of nothing that sounds better. If I lost it I would probably look at the latest options but as it stands this is still the one I would buy. I think all of this type of device are over priced when you consider what a small amp costs but for portable practice in a small space it can't be beaten. This Blackstar amplug is in my opinion the best VFM option available.Paul S.

Amazing bit of kit for the price! Clean, over drive and distortion channels in a small box the amps to headphones perfectly! Can’t really comment on the effects as not really tried them out! But if you need a tiny portable amp that connects to your headphone for practice i would throughly recommend! Just noticed it even has aux in so I can listen to my Fender tutors without having to have 2 different sets of headphones on the go!!! Total novice managed to get it working in 3 minutes without reading the instructions!Mike

Where do I start? Well, how about, this is the best tube amp I have ever played! 62 years with many guitars and many amps, some owned, some borrowed, and some tested in music shops, might give me a little credibility. I have loved a Fender Twin Reverb, made in the 50s that my uncle Keith, and my guitar mentor, loaned me for a while. It just sounded so good. Never could seem to find cash, or justification to buy a tube amp, but have owned a hal a dozen solid states. THEN THIS LITTLE BEAUTY! Having played the Twin for a couple of years, and others such as a Mesa Boogie, VOX's, and too many others to recall, THIS monster sounds like most of them with just little tweaks of the knobs and my guitar switches. I have played country, 60s and 70s rock, blues, finger-style instrumentals, gospel, etc. I believe this is the PERFECT combo, with the correct (JJ) tubes, a sweet (and dirty when desired) Seventy/80 speaker, and an amazing diversity of sounds, which works in every genre I play! I do not know how anyone can find reason to bad mouth this. I had it for 2 weeks, was asked to fill an absent, guitarist's spot at an outdoor venue, I took this little amp. We played to an area the size of a football field. I set the amp on 1 Watt, until I could hear it cleanly (behind me on stage), let the sound man mic and mix me in. Never had to turn it above about 4, with gain between 1 and 4, and many complemented me on my sound, and musicians asked me WHAT IS THAT LITTLE AMP? Those are the good points. I can only think of two piddly things I would like to see changed, and one would be a standby switch, and the second being a way to run the external speaker WITHOUT cutting off the amp speaker. Until then, I will just keep playing this sweetheart amp, and enjoy the statements about "my sound," and the question of WHAT IS THAT LITTLE AMP? Keep playing everybody…and maybe buy one of these. I do not believe you will regrety it.New User

These amps are fantastic, and at these bargain prices you simply can't go wrong. I upgraded the reverb tank in mine to a Mod and changed the speaker for a Warehouse GC12. OMG, this thing is a beast! Another WGS option I've seen people use is the ET65 for a more British tone, also with good results. The stock speaker is not too bad, but this one simple upgrade of swapping the speaker takes the amp to the next level. It just sounds awesome. The upgraded reverb tank is also an improvement, but not as much as I thought it would be. If I had to do it over again I would just take out the stock tank and use a pedal for reverb and make the amp even lighter to haul around. The more important upgrade imo is the speaker. It really makes a world of difference. Grab one reasonably while you still can, the price keeps creeping up and up and up… !Jeff

After a number of FEDEX issues, I received my amp about 5 days later than estimated. It did arrive in excellent condition and was worth the wait. The Stage Right 611815 has a really sweet tone that sounds particularly good with the single coil pickups on my Fender Sratocaster Player. It breaks up nicely! The reverb works perfectly, and is fine for most playing but you might want an external reverb unit if you are playing Dick Dale tunes. A really nice feature for home playing is the 15W/1W switch, where you can limit the amp to 1 W (be aware that with sound, you have to increase the wattage by 10 times to double the perceived volume, so the 1W setting is a lot more than 1/15th as loud as the 15W setting). It is a bit unusual to have a tone control along with the more common bass, middle and treble controls. Personally, I would have labeled the Tone control as Presence, because that is what it seems to be. I have mostly been playing in the 1W mode with all the controls (including reverb) at 12 o clock, and that is working out great. As far as construction, the amp looks fantastic and gives a vintage look that hints at its tone! The dark grill cloth provides a nice contrast with the blonde tolex, giving a true vintage appearance. The retro red, jeweled pilot light and metal toggle switch complement the vintage styling Keeping with the vintage look, the control panel is chrome with retro chicken head knobs. As others have mentioned, the control names are a little bit difficult to read on the chrome panel. After you use the controls once, you know where they are, so does it really matter (I noticed the blonde version of the Fender Blues Jr also uses a chrome control panel…probably where Monoprice got the idea)? The tolex is neatly installed and glued, at least the parts that are exposed. The leather handle is also reminiscent of old school amps. And I really like the metal corner protectors…very nice. As proudly announced by a badge on the front panel, the amp is equipped with a Celestion speaker…a Seventy 80 The only criticism of the construction, and it is minor, is that the 8 external screws are not chamfered properly to mesh with the finishing washers, which result in the screw heads protruding above the washers. The amp has a jack for an external speaker. When you plug in an external speaker, the internal speaker is shut off, as is common with guitar amps. The reason is if you plug in an external 8 ohm speaker and the internal speaker would still be on, a (combined) 4 ohm load would be presented to the amplifier, which it is not designed to handle. The back is open. The line cord is not detachable, but can be conveniently stowed in the back of the amp. The amp has an effects loop, which I have not tried yet. The amp is now equipped with JJ brand tubes and a metal, two spring, reverb tank, which are upgrades from the original issue I wish I could find a nice, economical (i.e. $20) dust cover for the amp. The only ones I can find are priced at $50 or more, a bit much for protecting an inexpensive amp. In conclusion, the Stage Right 611815 amp looks great and sounds great, and I highly recommend it.Chris

What a cool little invention for any guitarist to buy for themselves, or what a cool gift! This ultra-portable and kitschy stick-on speaker is a must-have for any guitarist. It is rechargeable and can last up to 3.5 hours on one charge, they look really neat and the sound produced is so surprising! I am honestly surprised they are as affordable as they are. This is a no-brainer gift for the guitarist in your life.Lady Landa

This thing is so cool. For a little speaker, it sounds incredibly good, and Im glad it has effects. Its fun to take my guitar out to the yard and just be able to jam away and have it sound decent. And its definitely loud enough, sometimes too loud, but you can control that from your guitar volume. My hats off to the guy who designed this!radius9999

Product works as described, really nice tone for what it is. 3 stars only because the model I ordered was different, I received the Heavy Metal Model, includes phase instead of Chorus. Also the grill is chrome instead of blackempo470

I was really surprised at how good this amp sounds. Years ago I tried Line 6 and was not at all happy with the tone; but this is another story. It does take me awhile to dial in a specific classic rock tone, but when I do, it sounds better than any other amp that I've tried. I have tried the Marshall Code, Blackstar id Core, Vox Valvetronix, Boss Katana; as well as some all tube amps. The only other amp that is a close 2nd is the Fender Mustang GTX; also a great amp. The Spider V is fairly easy to operate. It offers lots of choices for amp models and cabinets. I like that it has variations of a mic'd cabinet. The parametric eq is a plus. I haven't played around too much with the effects yet, so I can't comment on that. The only negative thing I could say is that when you're editing a preset and want to hear how it sounds before you save it, you only have a short time before it goes back to the Home Screen. This really is a small price to pay for the quality of the amp and all the versatility it has. I like the App too. Musicians Friend got me a great on this as well; and their agent is following up making sure that I'm satisfied. The funny thing is that I came across this by accident. I placed an order for a Peavey amp that was on back order. I called Peavey multiple times, but they never returned my call. I also emailed them, but they didn't respond to that either. As far as I'm concerned, Peavey doesn't have any customer support.crrkr

Been playing about a year, so my review is from the perspective of a complete newbie. The things I like- Lots of presets, mobile app functions, computer interface, and loads of user created effects available. Nice and loud, but no real basis of comparison to say if clarity is better or worse than other comparable amps. Don't likes- The micro-usb interface. I had to get an adapter and it's just not as good a connection as nearly anything else would be. IMHO, micro-usb is far too flimsy. Connecting to PC is far more problematic than just using the spider mobile app. It's probably a little more complicated than it should be for a beginner, but it's feature rich for the money.Nic T

I had a Line 6 120w amp for years that I regrettably sold a while ago and was looking for another amp. I looked at all the amp reviews I could find and decided that the new Katana was the way to go. I got the Katana home and absolutely loved it but the second day I had it it started a really loud buzzing that I couldn't stop. It probably was an easy fix but the fact is the amp was way too powerful for my purposes and their software wasn't compatible with the new Catalina OS. I returned and started looking again. I saw the 60w Spider V and the price was excellent so I made an on the spot decision to buy another Line 6 and I'm really glad I did. The tones this amp can get are incredible. There are so many amp models and cabs that you can dial in pretty much any tone you want from a crispy snapback country clean to the most vicious heavy metal and everything in between. You can use the presets as they are or you can use them as a baseline and tweak to your own liking or you can start from scratch and build your own rig from the ground up. The controls are intuitive and easy to use but there are some features where you'd have to be a professional to really know how to use or even care to use. The software and the mobile app are so easy to use and give you all the options at your fingertips. The amp comes with a lot of presets that I find are completely useless but there are a lot that are excellent as I already talked about. There are only four empty slots for your own custom presets and I wish there were more but if you use the mobile app you can have your own tone library on there. I bought the FBV3 foot controller so that gives me a lot of flexibility to have various effects. One of the limitations is the lack of good effects though. There's enough that if you work at it you can get a decent sound but there could be some better ones. Overall I would recommend the amp. Don't listen to the naysayers or the amp snobs, it's a quality amp and extremely versatile.Just Plain Joe

The good: small, portable, can run off batteries. The wireless connectivity is really nice. Sounds decent for what it is. The bad: The interface on the unit itself and the app are confusing to say the least, and you are pretty limited in the use of effects. The ugly: all those free Katana patches being posted on the Boss site? Incompatible. All the patches for regular Boss Katana amps WILL NOT WORK on this unit. Thanks for that Boss.Alexander

Overall: I may be mis-reading the manual but I've yet to figure out how to keep the wireless transmitter charged. I'm not new at this having gotten Line 6's wireless transmitters when they first arrived on the scene. They were easy to use and worked as advertised. While I am a huge Roland/Boss fan, I'm thinking they may have missed the mark in the "ease of use" category on the Katana Air. From a sound perspective, the amp, when plugged into a wall socket sounds great; just what you'd expect from a Katana amp. And when the transmitter is fully charged, the same can be expected. The problem arises when trying to figure out how to keep it charged. When running the amp on batteries only, this seems this seems to be problematic in that the amp stops charging the transmitter when the batteries are low. The problem is you don't know the transmitter is dead until you try and use it.My most predictable approach is to plug in the amp with the provided DC cable and do my charging while the amp is "hard-wired" to the juice coming from a wall socket.Once the transmitter is fully charged, in this manner, I can disconnect the amp and run it on a fresh set of batteries. This will afford you a "temporary" wireless operation. The transmitter that I received didn't have any where's near the claimed lifespan. I'd be curious to see how other's experience with the Katana Air played out. I will keep fiddling with the KA and if I discover what it takes to make it truly wireless, I'll get back to you in a follow up review. Strangely I did keep this item, hoping for a downloadable software cure.There is a nice free ap that accompanies the KA…..It allows you to change all of the amp's audio settings and to download free patch sets. This works well with my iPhone 7+.Martin

I've been seeking a modern, portable, reliable practice amp that can satisfy BOTH Acoustic and Electric guitars since Line 6 introduced their Amplifi series. I loved the Amplifi's techie saturated concept but no matter how bad I wanted it to work… it was always a low-fidelity 'noise' amp first without the ability to produce clear, hi-fidelity sound for either my acoustic or classical guitars. Designing an amp that can accurately reproduce hi-fidelity, low distortion sound begins with a good designed, quality build and above average components. As the old proverb states, "You can't make a silk purse out of a sow's ear", you can build a noisy amp but don't ever expect it to reproduce quality sound. Amplifi is the sow's ear. I thought about testing their newer Amplifi 30 but after many bad experiences testing a 75 and reading that I was not alone … I lost all confidence that they could do HiFi right. The Katana Air checks many of my must-have boxes and it worked without a hitch. It was designed as a small practice amp and not a single solution for all your gigging needs. Adding in the convenience features like smart-on and multiple wireless features that include power/updating/tuning/modeling/backing tracks/guitar, makes this the practice amp I have been waiting a long timefor. Finally, I can take an amp sailing without worry of 'butt cleats' or adding more hazardous lines to my boat.pete1tod

So far so good. A little hot with active pickups, def functionally. Appreciate the aux in to feed music or backing track while practicing and very portable. Worth the price.matta2z76

Had my reservations about buying this, a cheap headphone amp, as I have had others in the past and the o/d or distortion always sound awful. Don't get me wrong it isn't replacing my Marshall amp, but for a really portable and handy headphone amp it is great. I can use this, and move, whilst the kids are in bed, no more having to be 2 mtrs from my big amp….. As a practice and experimenting tool I love this!gastall1978

It's better than expected, though the design might not compatible with some guitar models. It requires an AAA battery. Works pretty well with any headphone. It also has an AUX port so that you can plug and play any songs you like and jam along. Thumbs up from me!wamin0

I bought this amp to use in a limited space and at a low volume for very low cost. It obviously doesn't compare to a normal size amp in quality but for being a practice amp it is perfect. Many reviews across the web say it loses power or sounds bad after a short time, but its literally as simple as changing the battery in my case. The manual even says to change the battery if there is an issue with sound, and the battery that comes with it isn't really the best and doesn't last long. It has great sound at a low and mid range volume for the little power it actually has but when you ramp it up it does sound a little distorted but not bad at all for $23-$29. Hopefully my review helps someone get a decent product!Lucas

While you certainly could use it in the studio for certain alt/auxiliary tones and/or layers and achieve fantastic results (producer/artist discretion advised), It's not meant for that. It's meant purely for being able to enjoy playing electric, untethered, while wandering about randomly and/or practicing. …Whether outdoors or indoors. …At home, in the park, around the neighborhood, at a camp site or a BBQ, wherever. Perhaps even during your breaks at work. It's not meant for playing in a full band situation (especially with drums), nor is it meant for getting a half-stack sound (or even normal combo-amp sound), for a fraction of the price, during a high-end studio session or full-on concert. It's a fantastic tool, meant to serve a single purpose. Choose and use your tools accordingly.Cristyn, E

mini-amp works great as a travel amp, or playing early in the am when ppl are sleeping lol it fits perfectly inside my hardcase, along with my electric guitar, headphones, tuner, cables, etc. performs as expected.. dont look to be amazed at its performance lol but for practice/travel its the perfect amp. has a heavy grind for chunky metal riffs. doesnt pick up the p[inch harmonics that great, but they do come through. the clean setting is great, too, and for a tiny little fkr it really kicks pretty good! had my finacee yelling at me to "turn that fkn thing down!" so, lol, it hits pretty hard for a small little guy.. but like i said, dont expect it to put out the tones of a line 6 spider IV or a Marsall half-stack cuz it aint capable for that. it isnt designed for gigs lol so dont expect that kinda sound. but, i love this mini-amp; its my new best friend!da.davc.mcoumykeiu

Before I review, I would like to say I am reviewing this product from a perspective as a gigging instrumental acoustic guitarist. Had to do an outdoor gig with no electric outlets available, that's when i looked into buying this thing, and it did the trick. Also had to fly somewhere across the country to do a gig where the venue didn't have a PA system, and I was able to pack this in my luggage, and this little thing did the job. For a tiny amp only a bit bigger than a Kleanax box, this thing is plenty loud. It's able to emmenate the volume to within about a 500 square feet coverage. Even louder if you play a distored electric guitar, as electric gutiar pickups don't consume as much power as an acoustic pickup. This is the perfect amp if you travel alot and need to fit something on the plane, for your living room, as a practice amp, for porch picking, camping, small coffeehouse venues (under 500 square feet), busking, or any scenario where there's no electric outlet nearby. Granted, this small little thing will not replace a PA system or something like an Acoustasonic Jr. I do a weekly coffeehouse gig (about 500 square feet) with my Fender Acoustasonic JR, and one day, my Acoustasonic JR wasn't working, so I brought in this little Roland instead. Granted, it was loud enough to fill up the whole entire coffeehouse volumewise, and although I much prefer to gig with this as it's super lightweight and won't hurt my back like the Acoustasonic JR, the sound didn't have the full definition as the Acoustasonic JR, or a real PA. Because of the tiny speakers, you only get treble, no bass response, less definition overall. However, as a portable battery-powered amp, this thing is awesome. It also serves mutiple purposes, I regularily plug my ipod to this and use it as a home stero system in my room.sman-eNpbJ

Bought the Roland MC over 10 years ago. I still own it and thought a review might help someone shopping for an amp. In my opinion, the Roland MC is a great solo or small group, highly portable, extremely low watt, practice session amp. For electric guitar, it sounds great clean with a tough of reverb, but don't expect much bass or volume. IMO, the Overdrive setting is just OK, and the Distortion/Fuzz is terrible. Before I forget, buy the AC power adaptor as battery life is very limited, especially at anything but the lowest volume settings. For the built-in effects, the chorus button works fine for the simplest applications, along with the somewhat adjustable delay, but there are lots of limitations. Consider them a nice "toy" feature of the amp, nothing more. As a PA, I found the Roland MC very useful, and used it for years with my acoustic-based, rock band as a single mike PA during our quieter practice sessions. It provided just enough amplification for lead vocals to cut through 2 guitars and an electric bass playing at low to medium practice volume levels. However, as soon as we added a drummer, it was over for the little MC. As far as battery use, I font recommend it. I tried it once on Halloween dressed as Brett Michaels playing "Every Rose Has It's Thorn" on acoustic-electric. Terrible performance. People started singing along and a friend turned up the volume…the amp had no dynamic range and actually get LESS loud the harder I strummed the guitar. The ultra low wattage of the amp severely limits its usefulness in performance scenarios. My son took the amp to college and he uses it in his dorm room where noise levels must be kept low but prefers practicing with a Scarlett USB interface and headphones and is looking for an amp with more power. Anyway, I hope you found this review helpful.Bruce S.

OK, I purchased this amp because of it's DC power, mic and instrument channels and small size. I'll use it for busking or jamming, anywhere I want without thinking about an AC outlet. I did purchase the AC adapter which came in very handy initially, given the batteries it came with were so weak the amp would not work properly. At first I thought the amp was malfunctioning. Strange things happen when battery juice is low. In my case there was sound break up, like there was short or bad connection. With AC power or a fresh set of batteries, it works well. If small and portable is your thing and you want mic and instrument inputs, this might be just what you are looking for. I've sure had fun with mine. So far, good. As I said in the review above, don't expect a really full sound with low end bass. All things considered, if you do not need the DC power option, I would see no reason to purchase this amp.More harmonica, please

I just bought this amp with the Line 6 FBV short board; they work well together of course. The amp is a lot of fun with the looper and presets and the endless ways you can tweak your tone. I love the amp but there are a few things which could be better. You must use a 2 gig or smaller SD card or it reboots if you try to save to a bigger card. So just get a bunch of small Sd cards before they are unavailable–only a few places still have them–which is kind of a pain. It does record nice but I haven't figured out how to record the mic input and the guitar input at the same time, so I always have to do two tracks. There is a switch which switches the input for recording back and forth from mic input to guitar jack. With the short board you can turn the looper and presets on on the fly, but you must put the foot pedal in the recording mode, and when the FBV is in the record mode you have to switch it back to channel mode to switch different guitar tones. So to switch to a different guitar tone you have to do another track to reset it. Anyway, I just thought these few drawbacks could have been easily figured out and fixed. Hopefully the next generation can take the more available SD cards, record more than one track at a time, and make the FVB do all the functions in one mode. However, it's nice having all the gimmicks for having fun in one package. Even thought I give it four stars instead of five, it "is" worth the low price, and I would buy it again knowing what I know now.Songwritunfool

The Line 6 spider jam changed my life in many ways. First and foremost you can save every idea that you come up with! 2nd it helped me to become a songwriter, it has everything you need so you dont have to rely on other people showing up to practice. Its allowed me to put the time into writing that I never could before, because face it most people dont want to rehearse 7 days a week, or even 5 for that matter! I thank God and Jesus for leading me too this life changing built in studio in a guitar amp!Skip Farfugnugen

If you are looking for a versatile and fun practice amp that you can record and gig with, this thing Rocks. I am primarily a bassist and just learning how to do leads on guitar and this amp fit the bill perfect. It does not have the warmth of a top of the line tube amp, but I did not need that as an intermidiate player. This thing has pretty awesome effects and tone varieties for about a couple hundred varieties and most I will never use. You can record, you can plug in a mic or a bass, you can jam tithe rhythm tracks, it has headphones so you play without waking the wife or neighbors, and a built-in tuner! That is just what I have discovered so far! The price makes this the perfect amp for practice, recording, and even small venue performances (half way up on the master and it is loud!) the only thing is it takes time to figure out and discover all the tones and capabilities, but that is also half the fun! Also the clean tones are good but not great. The distortions are fantastic! Not that the cleans are not useable, but they are bit thin for me. HIGHLY recommend!! Have fun!DFW_Bassman65

Because the Stage Right 5-watt tube amp (#611705) has control knobs only for Volume and Tone, I found that I get the best-to-my-ears guitar sound when I put an equalizer pedal between the guitar and amp and then adjust the equalizer to the tone that I'm looking for. On the guitar the Volume and Tone knobs are set fully open and on the 5-watt tube amp the Tone knob is fully closed and the Volume knob is set to the volume level acceptable to the environment (for home practice the Volume knob is set to level 3 at full 5-watts). The Stage Right 5-watt tube amp is my first tube amp after having used modeling amps for at least five years. I had heard that tube amps more often than not sound better than modeling amps. After now having experienced using a tube amp I agree that tube amps (at least the Stage Right 5-watt amp) sounds better than the modeling amps I've used (which to me sound great too). If you're looking for your first tube amp (like I was) or you are looking for a low-watt tube amp for home use then I highly recommend the Monoprice Stage Right 5-watt tube amp #611705. Review about Monoprice customer support: The 5-watt tube amp that I initially received had a cosmetic defect (a hole) on the textured surface on the front side of the amp. The Volume knob when set to fully opened level 10 produced normal speaking level sound instead of the noise-complaint loud volume that I expected. Monoprice customer service was great and easy to work with in submitting an amp replacement request. I described the problems, sent pictures of the cosmetic defect and a video demonstrating the Volume problem. After Monoprice customer service reviewed the pics and video they sent me a free shipping return label, a RMA label, and they ordered me a replacement amp which arrived within 7 days after I submitted the replacement request. The replacement amp that I received had no cosmetic defects and the Volume knob set to max level 10 is loud enough to generate noise-complaints from neighbors, though I normally use the amp at Volume level 3 for home use.New User

For the price (I got it when priced $119) it is fantastic. It's simple, straightforward and sounds good. Nice warm tones. If you're a fantastic guitar player, this amp will sound fantastic. If you're an okay guitarist, you might want to invest in some pedals (or just keep practicing). I only say that because it is very clean and bright and it really shows off what you're playing. (I've been known to hide my sloppiness with reverb, distortion, etc.) BUT It does take pedals well – thankfully! Adding a good reverb pedal, delay and an overdrive to go along with this little guy is a good idea. The Pros: Value to Price ratio. Looks well built. Warm tube sound. The handle (yes I am talking about the amp's handle) is nice! Better than I expected. In fact, everything looks pretty good (except the cheap control knobs). 5 watts is plenty loud for home/recording use. The Cons: Good sounding, but there are better sounding. Please don't buy this thinking that this is a $500 amp. It is not. But sub $200 it is a good one. The chickenhead knobs are cheap looking. I took them off and painted them. But that's a dollar or two easy fix (if it bothers you at all). Overall: I totally recommend for $150 or less. Probably for $200. If the prices climb too much beyond that, I think there are other options. If you want to jam at home and record with it, I think you'll be happy.Brad

The Monoprice 5 watt guitar amp arrived just a few days after ordering, and arrived in good shape, due in part to the excellent shipping carton. Upon taking it out and inspecting it, I could find no flaws in the cabinet, and due to the cream color of the covering, it seemed a little bigger than I was expecting. I plugged it in, let it warm up for almost an hour, and then plugged in an ES339, using no pedals. At first, I wasn't all that pleased with the sound I was getting, but it was my fault. I had it adjusted as I do with my Albion Hybrid, but that wasn't the way. I found the best sound came from turning the Monoprice all the way up, and then use the guitar controls for volume instead. That did it, and the little amp came a alive in a big way! Sounding very similar to a Fender champ, it could go from nice clear tones to crunchy heaven with the ES339's humbuckers. I plugged in a Strat with an HSH configuration, and the single coil really made it sound Fenderish. Sweet. The only thing I found one might improve on the amp, is the speaker. As such, I plugged into the built-in external speaker jack on the back, a little Randall 8" cabinet. That really did it for me. The sound was fantastic through the entire spectrum, and was loud enough to be heard down the block. I then bi-amped it with the Albion, and the sound had all the creamy goodness I've been seeking, and that is how I now have it setup for daily use. That said, there's nothing wrong with the stock speaker on the Monoprice, and I suspect it will satisfy most users. Am very happy with this purchase, and glad I bought it for such a great price. Almost every electric guitar player could find a use for this amp. Buy before the price goes up, or they quit making them!T

This unit sounds great, works great and makes the workflow jump to the next level. I'm running 4 amps through it, 3 cabs and a UA OX and it's just made a world of difference. Switching is clean, I can't tell any tone changes, amps are protected if using properly, it's dead quiet, is simple to use and is very clear for what amp/cab you've selected. With my rig now, I feel similar to how it does with modelers with the benefit of the analog amps/tones I love. Change flavors and sounds on the fly and make decisions best for the moment without losing your creative flow. I highly recommend it.JMontoya

Bought this amp based on many reviews on youtube, looked at many other models first but am glad I decided on the Amplifi 150. Also bought the FBV Shortboard MKII, a must have in my opionion, more on this later. Amp has excellent sound and can be used as a wireless bluetooth speaker. When I downloaded the Amplifi app that is when I really found out what this amp could do. You can play a song from your music library through the app and it will quickly find/display "presets" from the cloud to try. If you find one you like you can save it the way it is or edit it to your taste. With only the amp you can save 4 presets, by adding the shortboard you can save 100 presets, in 25 banks of 4. The shortboard also comes with a built in tuner and wah/volume pedal. Using the app you create your own sounds too. Choose from 200 different amps, many different stomp boxes, delay, reverb, modulation effects. Has noise gate, compressor, equilizer and volume. It took one short call to Line6 support to resolve a few issues I had initially, easy common sense errors on my part (how to store and retrieve the presets and how to increase the music playback so it was at the same level as my gutar). Once this was resolved I have had nothing but fun using the AmplifiErt68

Kudos to Line6 for such an innovative product. First of all, this is not a tube amp and Line6 never claims it to be…so please don't try and compare this to tube amps. It synced to my 3rd Gen iPad instantly and very quickly found tone suggestions for all my songs…even some of my own band. Some were dead on perfect…others required a little tweaking to get them to my liking. This depends on what kind of guitar you have plugged in – single-coil Strat, humbucker Les Paul, etc. The Tone Editor does a great job and is very intuitive. The included instructions are pretty lame; they basically show you how to plug in your guitar, turn on the amp and sync to an iOS device. After that, you are on your own to find more information. Luckily, the Line6 website has helpful videos and a great user forum for info. I had to update my firmware from 1.02 to 2.01 to be able to play all of the 100 mfg presets. Originally, I only had the 4 presets. The upgrade was easy, following the instructions on the website. This thing is plenty loud and I think it has a great tone and endless possibilities. I use it mainly for practice and it serves that purpose expertly! Song reproduction through the five speakers is excellent.Stanlo

This "amp" (it does more than most guitar amps) is extremely versatile. The secret is in the bluetooth connection to the Line6 app called Aplifi (free download) which allows you to edit your patches on your IOS device (an ipad is much easier than an iphone). Pick from 80+ amps, a large selection of pedals and effects, and drop-and-drag them into any order you want – then hit SAVE and you have that sound at the touch of a button. You can share your sounds with others via the Line6 library – and you can download other patches as well. The unit has 4 preset buttons – so your first 4 presets are accessable even if you don't have the app, but you really need to the app to edit the patches. Match this with a Line6 floor pedalboard (make sure you use Cat5 PATCH cable and not CROSSOVER cables) and you've got a great rig. It's loud enough that you can hear it on a stage in a club against other combo amps. There are a lot of modeling devices out there (Line 6 boards) but the trick is finding the full range flat response speaker system that can let you really hear those sounds correctly – as if you were plugged into a recording console. This until has all the editing ability AND the speaker for the amp. It also doubles as a great bluetooth speaker system – so you can play yourspotify tunes over this with plenty of clear power. Finally, it's stylish that you can have it your living room and not look like Guitar Center. The 150w version is loud enough to keep up with most live gig bands on smaller stages (and most venues would mic it anyway). It doesn't have an option for a extention speaker or line out (to a mixer of FOH) but you can record from the USB port, so there's that option. If you have versatile playing style (I play in several cover bands so I need to go from Taylor Swift to Bruno Mars to Journey to John Mayer) it's a great purchase. No pedal hassles – easy to program – and focus on playing!joes-bar-and-grill

Nice little kit! Instructions are pretty clear and it's certainly not overly complicated to build. Having some amp repair/building experience helps, but I'd say even a beginner could buy this, build it, and be playing it within a day or so. Once built it sounded pretty good as well. Fun to swap tubes around, substituting the 12AX for a 12AT, AY, or others. The 'effect' changes on the pull switches are pretty subtle, so don't expect anything dramatic there. But, the amp makes a great platform for learning, and even 'expanding' from the original design. I've put an EIA connector in the back of mine so I don't have a cord sticking out. I put some tall 'feet' on it so it would clear a speaker box handle. And, the power transformer is suitable for adding a 6CA4 rectifier, which I plan to do in the future. I'll have to move the filter capacitor section around some to make clearance for the socket, but it's a 6 volt 9-pin rectifier, so will work perfectly in this amp. I might even 'upgrade' the output transformer….or play with some yellow jacket type adapters to try a different output tube. In all, a lot of fun to build, sounds great for what it is, and I'm very glad I made the purchase!! A 'GREAT' value!!!Tom

This is a great kit. I wanted to build a small amp so i started researching schematics online. Then i found this kit. All the leg work has been done as well as step by step instructions. I just started it so i can’t comment on tone, but the ease and design of the kit is excellent. Full parts list, schematic and instructions include. It gives you a proven simple platform to start with and you can add your own modifications if you wish. Thanks MODRonnie

This amp is FUN. The sound quality is great, and it is packed full of amp models, effects, and pre programed drum loops. That combined with a 40 sec looper, and it's become the most effective practice tool I own. And it's so simple, I don't need a bunch of equipment, it's all in the amp. For me, it brings the fun back to practicing.Russ

This amp has a great range of sounds, including some earthy grungey stuff, and weird vocoder setting. The most all-round versatility of this unit is a combination of the Rhythm section, the separate input and control of the Mic, and the Looper section. With up to 10W of output this unit can entertain more than just yourself. I like the tri-select of output power, (especially when the missus wants to watch tv!). The footswitch to select between effects, rhythm and looper is more essential rather than desirable, yet it cost me another $100+ to buy, which seems like a lot for just switch (although it's heavy duty). The only other downside is the rhythm tempo switch, which needs a guess in the time between button presses to alter timing. This would be better done and made more repeatable with a rotary switch. Great little portable unit, and my new GoTo.David M. C.

Good guitar amplifier which is small, easy-to-carry, but powerful enough. Especially love the power switch feature so I can run it as 1W in my room without driving my roommate crazy.QI

The Loudster is an excellent piece of kit for anyone running amp modeling pedals. Plenty of power to drive my V30 2 x 12 cab. Well worth the money. Rock OnDonald
