Positive GridSpark GO 5W Ultra-Portable Smart Guitar Amp, Headphone Amp & Bluetooth Speaker with Smart App for Electric Guitar, Acoustic or Bass

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!

Great for an apartment dweller.Price was great, $120!

This 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.

I’ve been looking for a small headphone modeling amp to use with my electric violin for practicing at night in my apartment. I tried a couple other pocket modeling/headphone amps but had issues with latency and sound quality. Picked this little amp up and it’s a game changer! Sound quality and effects are phenomenal! Even using the amp’s speaker it sounds surprisingly good. It’s roughly as loud as an average acoustic violin with enough volume to accompany an acoustic guitar. After a day of playing with this little amp, I purchased the next size up as well to replace my other portable battery powered amp. The app works great and makes dialing in that exact sound easy. I came in expecting a crappy sounding amp that would only sound good through headphones along with some lackluster effects. What I got was one of the best musical tools I’ve ever purchased.

This practice amp is powerful! It has great sound. Has a large selection of effects. Very portable. A great value for the money. Sounds great when I use it as a Bluetooth speaker.

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.

This is the best little amp I have ever bought. It’s made very well and the coolest thing is that you can connect it to your phone or tablet and play backing tracks from an app like YouTube while your instrumentis plugged into it. And it pumps out the sound of your instrumentand the backing track from YouTube at the same time. I just got through jamming for over an hour with the amp doing what I described above and it didn’t even phase the battery. I am completely satisfied and pleased with this purchase. I havealready recommended it to several friends that are musicians also.

The sound from such a small amp is amazing. The app is easy to use and provides flexibility with tones, using backing tracks and practicing over any song. It is well made and much easier to carry than my Fender Deluxe.
