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 William Fowler4th Jan 2024

This is an incredible amp for home practice. Being able to load a multitude of sounds in seconds and have enough volume to comfortably fill the room without being too loud is fantastic. A lot of people mention the bass in the speakers - it does have more bass than some other amps i've used but not enough to make an impact to it's core function as a fun practice tool.
