- 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. - 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. - BradNifty Little GadgetJust 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.
