- HighRiver ForestRunPositive Grid got it right with the Spark GoI picked the Spark Go up on sale recently and I'm really glad I did. I already owned the Spark Mini and knew the quality that was built in so I didn't even think twice. Both are bedroom amps playing different guitar setups (a Strat on the Mini and an Epi SG on the Go). Others have said it and it bears repeating that it plays much bigger than it looks. The tone a bit deeper than the Mini with more bass present (the Mini carries more mid-range by the default settings in my opinion). For the money, this is a high value and high-quality small amp that holds its own. It also takes pedals well as I have a Boss SY-1 and a EHXtortion in front of it. If you are on the fence about purchasing the Spark Go, I say 'Go for It'! Note that I don't talk about the app because I don't really use it, I'm fine with the default presets.
- Open and honest reviewer.Best portable practice amp, barre NONE! GET ONE!This is a 6-7 month review. Let me begin by saying I have put this amp through it's paces and it STILL delivers probably the best sound, amp per amp lol, than ANY and I mean ANY other micro amp in it's category. It has thousands of settings and combination of settings and amp emulations that can range from sparkling cleans to death metal. If I was to suggest an amp to a beginner or pro show needs a travel companion, THIS IS THE ONE. The price is affordable, thankfully, and it's small enough to fit in almost every guitar case. Rechargeable, easy to set and forget, and has a tuner. If you need a review to make a choice, trust this random Amazon review and I'm sure lots of other reviews. THIS MICRO SPARK ROCKS! Literally!
- ReviewerKnocked it out of the parkThis pocket-sized guitar amp is seriously, ridiculously good for the money.
I've owned a number of amps including modeling amps, tube amps, solid state, etc. It can take a lot of tinkering to get the sound out of them that you want. I mostly want a nice clean sound without too much reverb or a hard driven fuzzy sound like that of Clapton when strumming in overdrive.
Let's start with the sound output: It's *really* good for its size. No audible distortion even when the volume is at max and some of the drive pedals push it beyond its normal volume. Great bass, too.
Modeling abilities: Infinitely customizable. The community is also enormous. So many people have contributed great amp/pedal combos so that you do not have to start from scratch. Just find one that's close to what you want and modify from there. The preset buttons are awesome, too.
Bluetooth: This thing works as both a BLE device and bluetooth audio device, and has separate hardware output volume controls for EACH. That's so, so good. You can play built-in backing tracks, AI backing tracks, or your own music and control the volume directly on the speaker alongside your volume knob for the guitar itself.
Wants? Ideally, I'd love a dedicated button to toggle overdrive and clean (or any two pedal configurations of your choice). I suppose that you could do this with the hardware presets, but then you'd have to occupy all 4 of them with 2 different models in order to reliably switch back and forth at the touch of a button.
For reference, I'm playing on a well-set-up Fender American Professional II Stratocaster. It's rare to see such a small amp do such an expensive guitar justice, but I am immensely surprised. This is my new go-to practice amp for my office. - Nicolas RamirezIs great and is extremely portable.Great practice amp. I also have the Mini, and even though the mini is portable, the go just takes things to the next level. Sounds good and just a joy to carry around and put it in the gigbag or moving it around the house to play. Totally recommended.
- Guido GutierrezMoney well spentMakes you sound like the rig real artists use, but in your living room without bothering neighbors.
Believe the hype. This is the best guitar accessory you can get for the price.
The app has all the gear you could wish for and the ability for search for tracks in YouTube, and have the chords extracted makes it easy to play along and solo.
Battery is fairly decent for regular practice. - JordanTiny, powerful, and diverse!Powerful little amp that's perfect for travel. The app is a bit convoluted, but allows for a massive diversity in tone control, and offers the basics very easily. This little guy has fantastic sound quality you don't expect for something so tiny! Not as good as a full size amp of course, but honestly, it's not nearly as much of a step down as you'd expect. Only picky guitar snobs are gonna notice a difference.
Now, this little amp isn't gonna be as loud as your full size ones. But this is a good thing for me, as I have ultra sensitive hearing and prefer to just fiddle and jam on my own rather than play for a crowd. But trust me, it CAN get very loud, enough to play on a stage for a small crowd.
This combination of personalized utility, portability, ease of use, wireless power, high quality sound and range of volume makes it well worth the price tag.
Biggest downside is how the app frequently has issues initially connecting. Sometimes it takes a couple tries, turning it off and on, turning Bluetooth off and on, etc. But once it's connected, it stays connected for the whole session. - KaylaPowerful and easy to use!Got this for a gift for my boyfriend (I have one on my Christmas list too) and he LOVES it! We already have a regular amp, but this allows you to easily play anywhere without having to lug a larger amp around or need an outlet. It has great sound and the preset options make it so easy. We haven’t quite figured out our larger amp and how to get the sounds we want. This one has so many options but the presets allow you to start having fun playing right away, which is really nice. Would recommend, for sure.
- Ainsley M.Works as expected: It’s a tiny amp.Definitely loud and clearly enough for practice while traveling or in a small space. The app setup was easy enough, but I didn’t end up using it too much. I was happy to learn that the factory preset tones sound good enough to work with. The metronome and tuner are very sub par.
