Description

Classic Form. Modern Innovation.
As an evolutionary design, GP-150 keeps the iconic dual footswitch form with expression pedal, but modern upgrades stand out immediately. It features a dedicated power switch and a built-in 3000 mAh battery that provides over six hours of runtime (screen brightness level II), with charging supported through Type C or DC port.

A New Core. A Cleaner, Faster Experience.
If the exterior pays respect to tradition, the interior is a leap into the future. GP-150 features a completely redesigned operating system with intuitive drag-and-drop routing and deeper control of every parameter. You can load 12 effect modules and arrange them in any order. Patch capacity has increased to 200, with 100 factory patches included. The looper now records up to 180 seconds, and the drum machine features more than 100 HD patterns. Every upgrade inside GP-150 serves one purpose: giving you a smooth and effortless creative workflow.

More Control. More Possibilities.
Compared to the GP-100, GP-150 delivers a major jump in control and expandability. The redesigned interface, additional knobs, and new control buttons allow full operation directly from the unit. With just two footswitches, you can toggle up to six effect modules and access tap tempo and sync functions. MIDI control is supported through USB, BT, and 6.35 mm TRS. No matter how ambitious your setup is, GP-150 adapts with ease.
From design to sound processing to workflow, you can feel how new technology elevates the classic GP form into something far more powerful. GP-150 invites you to join us again and explore a new era of tone creation.
