Guitar Headphone Amp Schematic For Sale (2024 Update)

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

What a great sounding mini amp. I've had to use headphone mini amps for the last 15 years due to time constraints and location of practice area. I didn't want to use the precious practice time I had just to set up full size amp for only an hour or so and then return everything back to storage area. It was so much simpler and convenient just to plug a mini amp into my guitar, put on head set and play. Down side was always the quality of the mini amps I was using. I was getting them for around half of what a vox cost.. I always wanted a vox but they were expensive. After joining mf rewards club and making several purchases I bought my vox for about half price by applying my points to the purchase. I should have never waited. This vox is 10 times better than the cheaper brands. As soon as I opened the packaging and held it in my hand I could feel the quality. When I first plugged it in and started playing I got really upset. Not at the mini amp but at myself for waiting so long. I highly recommend buying this mini amp. Trust me. It's really worth it and you'll be glad you did.Horn

Cannot praise this device highly enough. It sounds great, and is ridiculously versatile for such a small device, comprising not only Gain, Tone and Volume controls, together with three levels each of effects options Chorus, Delay and Reverb, but also Clean, Crunch and Lead. Two AAA batteries are required (included), and give hours of usage. Just plug it into your guitar, attach headphones (decent pair of over-ear type are best, but don't need to be expensive) and, if wishing to practice over a track by your favourite band, simply attach an appropriate device such as a tablet or 'phone. If you require to free your amPlug2 sound from the confines of headphones, Vox also offer a mini, 2 watt, amPlug2 amp/speaker to which you attach your amPlug2 and play out loud (but not loud enough to annoy the neighbours. The wonderful Vox 50 watt amp/cab stack Mini Superbeetle Audio blue tooth speaker also doubles as a guitar amp, complete with amPlug2 compatibility, but at full volume, this would definitely annoy the next door neighbours, and possibly those further afield. The amPlug has given me new found freedom to play and practice without needing to wait for opportunities where it can be done without audibly intruding on the personal space of others in the household. I have subsequently invested in the equally good Classic Rock amPlug2 (and which, on balance, I prefer), together with both the aforementioned Vox Mini amPlug2 cab/speaker and Superbeetle Audio blue tooth amp/speaker stack. Basically, the freedom afforded by the amPlug2 headphone amp has reinvigorated my love of guitar playing, and I try to squeeze in some practice time on a daily basis. I even felt enthused enough to unnecessarily treat myself to a new guitar. This amPlug2 is real value for money, but it has inadvertently cost me a small fortune.johnclark1954

This unit is low end and it has bad sound. It’s very static-ridden even with high-quality headphones. It’ll get you by but I would absolutely look for a better version.John S.

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

I just completed my Mod 102 kit. An excellent experience! I was delighted with the quality of components, clarity of instructions, and, perhaps most importantly, the sound of the amp. It is very loud – currently running into my Fender Twin Reverb cab (2×12) and very sweet! I will be running it into a new 1×12 cab with a new Celestion G12 M Heritage 'Greenback' when I get a case for the speaker (on order). My only criticism (and something to look out for) is that the chassis is very nicely painted in gray gunmetal paint. Even following the directions to file all the holes, it is very hard to get a good ground connection at every point a terminal strip connects. I worried about this, and about 1/3rd of the way through the build, took an ohm meter to check all the connections, and as I had suspected, some of the connections were not great (9-10 ohms or so!) So I removed the terminal strips (with the components I had already soldered still attached) and scraped away the paint under the tabs of the strips to ensure a good connection. Re-testing showed virtually zero resistance. I'd strongly recommend scraping the paint away at all holes under the chassis before getting started on the build. Even better, suggest that Amplified Parts leave the inside chassis unpainted (at least around the important holes). Aside that one criticism, I am delighted with the kit and with Amplified Parts. Everything was delivered promptly and they are a class outift. I'll probably try some of their other kits soon.vpmerlyn

I spent three evenings building the MOD102. The instructions are very easy to understand and the amp has a great Fender sound. I had one grounding issue that was easily fixed with a little help from tech support, which was excellent. If you're good at following step by step instructions and can solder well this is a fun little amp to build. Only small issue is the labels. They could stand an improvement.Brandon

I just finished this amp build and it sounds fantastic! I also just finished a Marshall 18 Watt clone and I have to say that the Mod102+ holds its own very nicely alongside the Marshall. In fact, I will probably use the Mod102+ for recording because it sounds amazing at lower volumes (the Marshall is loud AF). Honestly, if I were only going to build one of them today, it would be the Mod. I'm blown away by the tone! Great kit with excellent instructions. Great bang for the buck. The parts all seem to be top quality. I love the old style cloth solid core wire, too. I find it much easier to work with than modern stranded wire. The labels are a bit lame but I covered them with packing tape as suggested before cutting them out and they look fine. If you're thinking about building an amp, build this one.danjbeckett

Amazing product,You can play your guitar anywhere ! From clean to crazy every sound you could ask for, headphones or speaker your choice! Buy and enjoy!burn_13

Brilliant little amp, good quality sounds, rechargeable for about 5 hours use, although the delay and reverb setting will use a bit more power. Sounds great through my powered studio speakers or just headphones. Highly recommended.davidfenderbender

I use it for electric mandolin for silent practices , the highs are smoother and cleaner than the ac30 model i borrow from a friendmofolkie

I am quite pleased with this headphone amp. I have been using it with a bass and am very impressed with the even frequency response and very pure-sounding tone. I am also using Shure in-ear headphones, and the combo just sounds right together. The clip on the unit fits onto guitar straps so it is convenient to plug in with a pedal patch cable and clip on near the bottom strap button. Having said that, I do have a few gripes with the unit that were enough to take away one star. For one – mine shipped with the volume knob turned all the way up. Without clear marking of what is max and min volume, this could be damaging to someone's hearing out of the box. While it doesn't get very loud, it's still inconsiderate to the musician. The other thing is the static when the headphones are being plugged in. Again, with the default volume at max, this isn't a good thing to have happen. I certainly hope nobody puts their headphones on before plugging into this… I would much rather see a different volume knob on this unit that clicks off when it is turned all the way down, especially because I'd prefer to leave my headphones plugged into this when I'm done with it (have to unplug them to save the battery). Overall it's worth the price and the simplicity is great for musicians. Just be smart when it comes to your ears and you'll enjoy this product.that guy

Well I don't like Electro Harmonix but I've purchased junk practice/travel amps from fender, and the especially bad VOX..really really the VOX is garbage don't buy the VOX. This one I currently use at work with a single pickup and it sounds really nice and clean. Warm not scratchy. So even though I've wasted some money on Electro Harmonix pedals this practice amp can't be beat at the price point they sell them for. You might get something with more bells and whistles than a volume knob for twice as much but if you want a simple clean amp this will do at this price this is a great little device. I rated it 5 stars because for the price it blows away the toys out there at the same price. This is a stocking stuffer a musician can actually use.bjq3srl

Got this Amplug Blues today plugged it into my Strat and it sounds great! and I highly recommend it! Now is it perfect? the answer is the usual NO. I think it can be improved on as follows. 1. Put a little color on the dials… the plastic is all black and the plug can rotate to different orientations. Would really be nice to have the dials stand out better with different colors. 2. Change the AA batteries to USB rechargeable Lipo battery. No reason to burn batteries when you can recharge! 3. My main change request is to have Bluetooth Audio In because you plug in the Amplug and then connect headphones (great for practicing). But to add audio to jam to you need to connect another cable to the Aux jack. So for me it just get's to be too much. Since nearly everyone has a smart phone it would be great to use Bluetooth for the Audio In so you can wirelessly play jam track and stuff without needing the 2nd cable. But it does sound really good and I'm keeping it!Harpster58

I regret, that I was mistaken in my previous review. I had claimed that the sound was great – but, that some functions were missing, after about a month of use. That is not true. I re-read the slightly, confusing, manual. The unit itself is – slightly, confusing* – but, it does work the way it is supposed to. In fact, you have a serious selection of effects – at least, three levels, of each one of, three effects – far more than other units in this category of headphone amplifier. The sound is incredible – the thing's got, big, b*alls! – and that, in itself, is worth five stars. Amazing job!
*The effects are split by two different buttons at two different ends of the unit, which makes it a bit uncomfortable.Dale Alan Bryant

I've been looking for a way to practice without having the hassle of amplifiers. I've always practiced my electric bass unamplified. I considered an acoustic bass but ultimately decided on this product. It works great for practice. Some other reviews complained about noise. There is some noise, but not enough to keep me from practicing. I wouldn't record with it, but hey, it runs on 2 AAA batteries, what do you expect? For the money I'd expect it to be made of better plastic. The case has a somewhat lightweight and textured feel. It would also be nice if it was Bluetooth capable for aux/headphone connections.Pete

I have been very excited with this wee amplifier. It plugs directly into the bass' output jack. There are dial-controlled volume and tone controls which work perfectly and provide well-designed volume and tone sweeps The sound has 3 press-button activated gain levels, and a small colored light which changes color to show which is switched on. Two options, with orange or red colors in the single lamp, are quite low in volume (too low I think) but the third, when the green light is on is excellent, potent with a bit of growl – think Jack Casady, I say! There is an output jack for headphones – plenty of volume available – and an input jack to run, for example, an iPad into the Vox. So, you can privately play along with any music you have stored on an iPad! Powered by 2 AAA batteries, which come with it. Absolutely amazing device. A beginner can buy a bass, use this amp without even needing to purchase a guitar cable, and be ready to begin. The "headphone" output can be plugged into an amplifier's auxiliary socket (my small Ampeg amps are wired to "center" a stereo input signal) or a home sound system using a mini-plug- to- 1/4" stereo converter jack and perhaps a mini-plug-ended extension cable, sold everywhere in various lengths. So one could practice and have the combined sound of iPad and one's instrument sent to an amp. You can overwhelm the Vox and make it bark by too much input volume from your bass or by suddenly too-hard pick strikes, but if you moderate that a little it is fine. Superb device!unclefot

I bought the single speaker unit after being unhappy with a Fender micro and the GC manager recommended the Blackstar. Home run. I was so pleased with it, I also bought a Blackstar bass micro amp with the extension speaker. Both are superb. My primary use for this guitar amp is for when I go cruising and/or when I know I'm going to perform with acoustic players. This micro amp fits into a day pack along with my laptop and Steinberger Spirit guitar (which I love, also from GC). The flexibility of battery or AC power is wonderful. The sound for such a small unit is superb. Night before last I played my UBass with the Blackstar micro bass amp & extension speaker at a uke (two of which were amplified) jam and my bass was plenty loud enough. Can this amp keep up with big amps? Of course not. But it's perfect for certain situations … and that's why I have a collection of various guitars, basses and amps.Bill C.

Bought this as my music room is rather small and I didn't want a great big beast of a thing taking up too much room. This kit is exactly what I was looking for. It has everything I need and the nice touch with the reverb delay and distortion is a bonus. I was impressed at how loud the system is for such a small item. I run it alongside a RC300, 4 pedals and Tascam 8 track digital recIorder outputted to Techics amp with Denon speakers. I feel I'm neglecting the wife🙄, I just unplug from the mains, pick it up and wonder into the front room and serenade her ….brownie points for me 😁 I do agree with another post about no being equipped with a carry handle or even better a couple of d clips on the side where you can attach a strap and sling it over your shoulder and off you go. As a bundle it's a no brained on price. Great product and at an affordable price..Great service from PMT. Had a few items off these guys had a slight one time problem with packaging but the guys sorted it really quickMike

Bought this for quiet playing both at home and in my camping van. So needed to be battery powered and small. The sound quality was only secondary. But as with all other reviewers, I found that this thing sounds awesome. Just yesterday, I miked it up and recorded it for a part in my current song. I'm using it mostly with a Strat, and it is quite a dark tone. Not like a Fender style amp. The IMF control can brighten that a bit – however the sound of the amp is pretty fixed. But it is a good sound. The delay is awesome for ambience. I live in a small flat, and in the past, unless recording, I would always just play unplugged. But now I always grab this little thing and plug it in. Far more inspiring. I'm yet to need the 2nd speaker. But the power supply is useful. PMT also did the best price online. Thanks.B M.

It sounds great especially for the price. The cab sim sounds nice and full compared to the clean. Plays well with all of my pedals.cjgp7524

The Vox AC30 G2 headphone amp is a fun piece of equipment. It is quite versatile in the sense that it has a line out, so you can record though your software, analog equipment or whatever you are using to record guitar. There are half a dozen built in guitar effects, which can be activated by pressing the FX button. The LED will light up a different color based on which effect is activated. This amp is powered by 2 AAA batteries. This amp sounds like the classic Vox AC30; it has a classic 60's and 70's British rock sound. So it's not gonna sound like an overdriven Marshall stack with that heavy mid guitar sound. It will get kind of a Brian May type of sound. This is a fun amp, and it is perfect for practicing quietly . The durability seems weak, it's lightweight plastic, so it will take time to evaluate the longevity of this headphone amp. But so far so good.tom

First off, I'm a dabbler and not a professional. I bought this so I could practice on my electric guitar without disturbing everyone else. For that purpose it is excellent. The package comes with a small instruction pamphlet which is tucked into the folded cardboard backing. It's easy to miss it. You need the instructions because it's not obvious how to operate the device without them. But the instructions are easy to download as a PDF from the manufacturer's website. You're not going to replace all your pedals with this inexpensive device but it does include an impressive array of built-in features such as tremolo, reverb, distortion, tone and (I haven't tried it) Rhythm. It does a great job of mixing the AUX input with the input from the instrument. I use it with my laptop and Band in a Box. Adjust the AUX level at its source (the laptop or player) to an acceptable level and then use the controls on the amPlug to adjust the volume of the instrument to your taste. Listening to the resultant sound through headphones is impressive.gixxernaut

If you want the straight up Brit Grit of the VOX AC30 this little device delivers great sounding tones.It sounds very good clean, and GREAT with gain added. The distortion from the gain is tight, very bluesy, and provides the crunch for classic rock. I have played an Epiphone 335, a Gibson SG, and Fender Strat through the device and each instruments sounded good. But, the amp really brings out the blues tomes on the Gibson and Fender. The amp gets LOUD, maybe too loud if you care about damaging your hearing. I like my music loud enough to hear it, feel it, and be inspired by it, and I can accomplish this with a minimal volume adjustment. There are three effect settings; tremolo, reverb, and delay, but they are basically useless to me because i don't use effects, and the effects cannot be adjusted to serve any useful, or musically desirable purpose. For example, a little bit of delay can be cool, but the delay on this device is enough to make you dizzy, and the same can be said for the tremolo function. Reverb too… who uses reverb anymore? I am a hard core blues and classic rock guy and I think reverb is dated… I am spoiled though, I play through Fender tube amps and bells and whistles are not really my thing. All i need is myself, my guitar and red hot tube amp and I am good to go. And the from this standpoint the VOX AC30 gets the job done very well. (It) is fragile and one must be careful handling (it) and the guitar while (it) is attached to avoid breaking (it), but if you are careful (it) is just fine. By the way, (it) connected to the guitars I mentioned earlier without any problems. If you want to jam like a mad man without bothering anyone, this is the device to get. It is good for clean guitar playing style, and for those who want to rock out. Not for heavy metal or thrash nonsense, but very good for solid blues and classic rock. Get one!Jim in the Box
