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  Type-C or DC port.
Display
The screen has been upgraded to a 2.4-inch HD color LCD for clearer navigation.
Dedicated Volume Knob
We added a dedicated master volume knob, color-changing footswitch rings, and multiple status indicators for instant feedback. The right output uses a TRS balanced connection.
Expansion Ports
Expansion ports allow expression pedals, external switches, and MIDI control. With a stronger hardware foundation, GP-150 is built to become the next timeless classic.

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 up to 12 effects 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.
