About This Item
Description
Want a floor processor you can practice with anywhere, cord-free? The GP-150 packs 200+ effects, SnapTone neural amp modeling and a built-in expression pedal onto a board with a 3000mAh battery good for 6+ hours, plus Bluetooth for playing along with a phone.
Why guitarists choose the GP-150
- The built-in expression pedal plus a single EXP/FS jack cover wah and volume swells without buying an external pedal.

- A 3000mAh internal battery with 6+ hours of runtime and USB-C PD charging means you can practice on a couch or a park bench without a power outlet nearby.
- A 180-second looper and 100+ drum patterns turn the unit into a practice and songwriting tool, not just a live effects board.
