Valeton GP-150

Multi-Effects Processor

Valeton introduces the GP-150, the next-generation digital multi-effects processor. This is not a minor refresh. It is a complete evolution. 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.

Next-Level Modeling.
A New Voice for a New Generation.

GP-150 is powered entirely by Valeton’s second-generation HD digital modeling technology. You get more than 200 premium effects based on the new architecture, supported by an upgraded 48 kHz sample rate and redesigned cabinet simulation for higher clarity and realism. To push even further, GP-150 supports Valeton’s latest SnapTone technology, allowing NAM file conversion and loading. It also supports third-party IRs with 1024 and 2048 sample points. The unit stores up to 100 SnapTone files with 50 curated selections included, plus 20 third-party IR slots. With all this tech working together, GP-150 raises the standard for tone quality in its price category.

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.

2.4-inch HD Color LCD 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 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.

PC: The companion software handles parameter edit, file management, firmware update and other operations. and GP-150 also works as a 6-in 4-out audio interface.

Mobile: GP-150 connects through BT and pairs with our advanced app for tone editing, wireless playback, patch management, and updates.

Built Around Your Needs.
Designed for Real Musicians.

Valeton has always focused on real-world user experience, and GP-150 reflects that commitment. Factory patches are reorganized and optimized for practical use, letting you instantly access iconic tones from artists, genres, and classic tracks without building patches from scratch. The headphone jack supports 3.5 mm TRRS headsets for streamers and online teachers who need clear communication.

Tuner: The tuner now includes cent display and multiple tuning templates that cover most alternate tunings. The USB port supports PD fast charging and reverse power to keep you prepared during travel. All these thoughtful details show just how closely we listen to our players.
