Electric Guitar Amp Created By John Deacon For Sale (2025 Update)

This little amp is quite amazing in sound and features. With the Guitar input, Aux In, and headphone jack it nails the features desired for practice. EQ/Gain control and volume can make a huge difference. I read the one critical review below about no bass or treble/AM radio sounding, etc…I don't get that? Probably doesn't understand the gain/vol/ and boost…or his was pre-owned and maybe had issues. Hey, if you're expecting the Fender tube sound of a Princeton or Vibrolux or Deluxe…get real, this is a 10 watt practice amp. For the money, it's a quality Fender product and does everything needed to practice.madillac09

This is doing the job I wanted. It doesn't have fancy effects like reverb, but it produces a nice sound for practice. I don't do public performances, so can't say how well it works in that environment. For the price it's a winner.lndi2007_yrggd7or

Im really disappointed with this amp. I know its not supposed to be super loud because its only 10 W, but I was hoping that the sound quality would be better. The sound reproduction frequencies are all mid range. Sounds like cardboard. Color is grey. Bass and treble tones are all but nonexistent. The eq is useless because speaker cannot reproduce bass and treble frequencies. The sound is very cheap and does not give a representation of the Fender vibe whatsoever. You are better off just playing your guitar with no amplifier at all rather than using this, because it make a good guitar sound bad. I equate the sound to that of an a.m. transistor radio. Its really bad. I actually read some of the favorable reviews on this amplifier before I bought it, and Im seriously starting to think that none of those reviews are actually real. There are better practice amps with better fidelity out there, and I would avoid this one if your ear demands quality sound.mrmarksiii

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

Every guitar player on God's green earth should have one. The different tones offered with the app inspire you to play differently. It allows you to play along with the songs you love, and download the tone. It also tells you the chord progression to the song. It's an amazing Amp, and if nothing else the GREATEST speaker in the world. I could absolutely ruin my neighborhoods night with the most absurdly clear version of my favorite songs. But I could Also practice at midnight with out waking up my roommates using my headphones.
Amazing tones made by professionals. If you care about being a musician… you need this Amp. This Amp was recommended to me by John Moyer… of disturbed.Teryn Surratt

As a practice amp, you will soon lose interest if the tone is thin, boxy and generally sounds like crap. The Spark is none of this. An incredibly wide range of tones are available via the app with sounds that you just don't expect to come from such a small package. The sound is loud, rich without the boxiness that you seem to get with amps loaded with small speakers. If you've used PG's Bias software, you'll be in very familiar territory – great emulations that have a depth that rivals some of the serious modelers available now. The effects, while not giving you a massive selection, supplies pretty well every type of effect you would ever need. The reverbs and delays are particularly good and while more than good enough for noodling at home, are more than up to the task of recording. The unit is quite sturdy with a timber cabinet and looks great – very traditional with an "English" type of styling. Using the Spark as a Bluetooth player for music is more than up to the task – good bass, clean mids and treble and loads of volume. The app overall is very good with some truly inspiring practice opportunities, though the function where the app analyses your playing and constructs a suitable backing track is hit and miss and is probably the weakest part of the app. Bluetooth connection for both control functions and audio playback is stable and very quick to pair with your device. Overall, I don't think you will find and amp sounding this good with the flexibility and functions available, from anywhere else and that is before taking into consideration, the extra functions the app gives you.Mick G.

I bought this amp on the back of all the rave reviews on YouTube etc. For me, it's just not a finished product yet. It feels very "beta". The hardware seems robust and of good quality. The modelled sounds are very good, albeit very bass heavy. But most of that can be EQ'd out. There are several problems I couldn't live with, and had to sell it on. The hum problem which is due to the supplied, un-earthed PSU was very apparent in my example. I contacted Positive Grid support about the issue in December 20, and as of selling the amp at the start of March 21, I had not yet received the replacement PSU. There are temporary workarounds, but I wanted the problem sorted permanently. As said above, the sound is very bass heavy. The amp models' EQ can be used to deal with the guitar tone, but music playback through the unit via Bluetooth has no EQ control, so the sound quality is very poor. In addition to this, the playback level is far too high. When using as a Bluetooth speaker it is very difficult to get the volume low enough using the tiny trim pot volume control for comfortable listening when sat in close proximity to the unit. The Auto Chords feature is a gimmick and needs serious work. It only works for E standard guitar tuning. For example, when listening to a song in dropped standard tuning such as "Yesterday" (guitar tuned down one whole step) Auto Chords will show fingerings for F, Em, A7 etc instead of the G,. F#m, B7 shapes that are required. At the very least, a "transpose" button is required to allow for dropped standard tunings that are very common. When using the tuner, you have to look at the lights on top of the amp. The app should have a screen that displays the tuner on your connected device when in use. The app metronome tempo can only be set by tap. It should have the ability for the user to enter the exact required BPM by inputting the figure required, or selecting the tempo with up and down or + and – controls. All of these niggles were too much for me to live with. Hopefully Positive Grid implement the changes in future releases, but I won't be buying Spark again until they do.Paul

It’s a powerful, cultured little rock amp. No need for gimmicks, it’s good enough to be what it’s supposed to be. (It looks ace too.)Reviewed by Absolute Music custo

Great budget amp that does not disappoint. Sturdy yet light and easily enough wattage for playing at home. I would definitely recommend it.kscott7073

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

I have the cousin of this amp the sp10 with only volume, bass and treble controls and overdrive button. The reason I'm making this review is because this amp might get overlooked and I believe it's a very decent practice amp. When I was learning to play guitar I only used the clean channel because the overdrive channel sounded horrible ie. fizzy. Couple years later, after getting better at playing guitar and developing proper touch, I realized that you have to use your guitar volume to add the amount of overdrive, distortion and fuzz. Basically, turn the volume on the amp to the desired volume level and then use your guitar volume knob to add in amount of distortion you want. You also have to mute strings otherwise you'll get mush. These amps are really musical if you know how to play guitar. The best feature is its portability and plug and play. It's loud enough for home use playing by yourself to backing tracks. For learning guitar you really don't need anything more than this amp, imo.Jerry
