Product Description

Play whenever and wherever you feel inspired with the Positive Grid Spark GO portable guitar amp — a tiny, app-supercharged beast! We're talking seamless integration with the acclaimed Spark App that's chock full of amps, pedals, Auto Chords, Smart Jam, 50,000 tones on the cloud, and so much more.

Jam-packed with innovation, Positive Grid's Spark GO delivers surprisingly big sound for an amplifier of its miniscule size. At just 3.5" high, it takes up almost no space but fills an entire room with mind-blowing guitar tone. Boundary-pushing computational audio creates the full, detailed sound of a much larger speaker, so now, it's simple to have a powerful amp anywhere in the house. Bring your amp to you, not the other way around! And another great feature? You can plug in headphones for immersive quiet practice, with MusicRadar describing at as the "best experience" they've had with "an affordable amp with headphones" — quite the endorsement!

Mr Matthew Farrell7th Feb 2024

It’s not difficult to see why so many of these amps have been sold, if you want an ultra-portable practice device that sounds good at low volume the Spark is an easy choice. It would be a strong contender even if the Spark app wasn’t as good as it is, but its ease of use, access to a huge tone library, (amp & fx pedal sims) hundreds of jam tracks and a well established online community are a huge bonus.

Fantastic little speaker far exceeds my expectations. Great for what I needed which was a living room amp that won't annoy neighbours but still able to handle volumne and clarity.

Great bit of kit for messing about with your sound. Tried it with acoustic, electric and even a bit of amplified harmonica. Run it through a bigger cab if you need more welly.
