    • Great little Amp! Amazing sound quality, battery life, mixer options.
Color: Black
I have a travel guitar that, I used to use a lot but the honey tone amp ate batteries, the set up breakdown time was annoying and the sound quantity disappointing, so I mostly stopped using it. I ordered this amp with low expectations but after playing with it I couldn’t wait to endorse it: I love this amp! Great sound, great build quality nice and compact. The app has one common feature I don’t Ike but is very powerful. Feature I don’t like: different amps and mixers are skeuomorphic forcing you to interact with pictures of physical Amps. Feature I love: you can play a track and have the app lift the guitar settings an apply them to your guitar. Volume is surprisingly strong and clean and distortion free. By far the best electric guitar accessory I’ve gotten in years. One physical complaint. I wish there was a way to have a rigid connection the the guitar. I bought a male male amp adapter hoping I can attach the amp right to the amp port (although this will face the speaker towards me rather than out). Ps - also doubles as a high quality Bluetooth speaker. ... show more

    • Must have
Color: Black
I love this speaker. Great sound and value. You can take it everywhere and keep it in a small apartment. It connects to your phone via Bluetooth and plays your music and the music from the phone together. You can download and customize the effects. It makes playing and practicing even more fun.

    • Great little mega multi-device!!
Color: Black
Love this little amp. Has built in tuner and available backing tracks. The ai feature will create a backing track for any melodies or riffs that you play.. The sound is great. High quality and clear. Perfect for practicing and jamming in the living room. Loud enough to hear and enjoy but won’t disturb your neighbors! Haven’t explored all the effects yet but what I have explored, I love!! Where has this been all my life?!? For the price, it’s a treasure!! ... show more

    • Knocked it out of the park
Color: Black
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. ... show more

    • Great item for practicing anywhere
Color: Black
Great little amp for sitting on the porch and annoying the neighbors lol. It’s perfect for practice anywhere and sounds pretty good. I just sat down with it and the app, the app is great and there are way plenty options. You can even pick a song and play along with it at varying speeds. This can replace a few other apps too. The price is a little high considering I purchased a real amp for not too much more, but I am still giving 5 stars. Good job guys! ... show more

    • Nifty Little Gadget
Color: Black
Just to flex my street cred (kidding), I've played guitar for 25 years and have several amps ranging from tubed half stacks to smaller, lo-watt combos, to a couple other battery powered amps because they're fun to play even after the neighbors go to bed. This is my first experience with a Positive Grid product and so far the impressions are good. I purchased the Spark Go to dip my toe into the world of Spark. The price is really good for what you get. At it's core, the device itself is essentially a bluetooth speaker with a quarter-inch input and 4 memory banks for configurations saved in the app. The app is where the real power is. It's fun to play around with the pedal settings and dial in a sound worthy of the 4 memory slots. I'm still trying to decide. You could theoretically use this without the app, but half the fun is configuring the sounds that make you want to practice and ultimately not have to use the app so much once it's all set up. The UX of the app is pretty okay. Lots of skeuomorphic elements that fans of GarageBand will find familiar. The sound is decent, especially for drives, modulation and delays. Reverb is laughable and barely audible through this speaker. It feels solid and a lovely little piece of kit. I wish there was a drummer built in, but bluetooth makes it easy to stream drumming backing tracks. Time will tell how this amp works down the road. Who knows if they stop supporting the app / device down the road and we all have fancy door-stops. But hopefully this is something... disruptive to an industry that will not be disrupted. The Spark makes it easy to get going and makes practicing more accessible. I'm still messing with the settings more than I'm playing the guitar, but i'll find my stride soon-enough. I would recommend buying this for any guitarist that's half-way tech savvy. ... show more

    • Positive Grid got it right with the Spark Go
Color: Black
I 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. ... show more

Nothing beats this. In all ways you can think of. Price for the product is absolutely awesome. Its so conveniently portable. Easy to hook up. Want to show off at a party? This thing fits in your pocket. I could list so many things Ive done with this little amp my review would end up a novel. Get the thing. If you are looking for a practice amp you can jam woth, has a tuner, a plethora of community made amp tones, AI made amp tones, AI drummer to jam with... seriously I could go on for days. Buy it. If you arent satisfied with it Ill pay for your refund myself😂 ... show more
