Complete Control, Streamlined Design
The Valeton GP-150 takes the iconic dual-footswitch layout to the next level. Designed for musicians who want a self-contained, modern tone workstation, it combines a built-in expression pedal with next-generation processing power.

Why Choose the Valeton GP-150?
🎛️ Real-Time Expression & Control
Unlike its siblings, the GP-150 features an integrated expression pedal, giving you instant, real-time control over volume, wah, pitch-shifting, and effect parameters. Combined with dual footswitches and a newly designed interactive interface, it offers a smooth, intuitive playing experience right out of the box.
🎸 200+ Effects & Flexible Routing
Powered by Valeton's second-generation HD modeling technology, the GP-150 comes loaded with over 200 premium effects. Run up to 12 effect modules simultaneously and arrange them in any order you like. Your signal chain is entirely in your hands.
🔊 SnapTone NAM & Custom IR Loading
Bring the world's best amps to your pedalboard. The GP-150 features SnapTone technology, allowing you to load NAM (Neural Amp Modeler) files directly. It includes 50 curated SnapTones with room for 100 total. Plus, you can load up to 20 third-party cabinet Impulse Responses (IRs) to perfectly tailor your speaker tone.
🔋 True Portability with Built-in Battery
Leave the power supply at home. The GP-150 features a built-in 3000mAh rechargeable battery that delivers over 6 hours of continuous playing time. It can be charged via a standard 9V DC adapter or its USB-C port, making it the ultimate grab-and-go rig for rehearsals, busking, and live gigs.

The GP-150 doubles as a powerful 6-in/4-out USB audio interface, compatible with Windows, Mac, iOS, and Android. It also features Bluetooth 5.0 for wireless tone editing via the companion app, and a 3.5mm TRRS headset output that is perfect for silent practice, live streaming, or online lessons.
