Valeton GP-150 Digital Multi-Effects Processor

The Valeton GP-150 is a next-generation digital multi-effects processor designed to take Valeton's popular GP platform to a new level. Combining second-generation HD modeling technology, over 200 premium effects, SnapTone/NAM support, third-party IR loading, 12-module signal chains and a built-in rechargeable battery, the GP-150 delivers an incredibly versatile guitar rig in a compact and rugged format.

With its upgraded 2.4-inch HD color LCD display, redesigned operating system, flexible drag-and-drop signal routing and extensive connectivity, the GP-150 is built for guitarists who want powerful tones and a fast, intuitive workflow — whether you're playing at home, recording, rehearsing or performing live.

Next-Generation HD Modeling

At the heart of the GP-150 is Valeton's second-generation HD digital modeling technology. The upgraded architecture operates at a 48 kHz sample rate and delivers over 200 premium effects, with redesigned cabinet simulation for improved clarity and realism.

The GP-150 also supports Valeton's latest SnapTone technology, allowing you to convert and load Neural Amp Modeler (NAM) files. Up to 100 SnapTone files can be stored, with 50 curated files included.

For even more tonal flexibility, the GP-150 supports third-party cabinet IRs at 1024 or 2048 sample points, with storage for up to 20 IR files.

Build Your Own Signal Chain

The GP-150 allows up to 12 effects modules to operate simultaneously, with complete flexibility over their order in the signal chain.

Its redesigned operating system provides intuitive controls and drag-and-drop routing, making it easy to experiment with different effects combinations and build detailed signal chains without complicated menu diving.

The patch memory has also been expanded to 200 patches, including 100 factory presets, giving you plenty of space for your own custom sounds.

2.4-Inch HD Color Display

Navigation is made easier with the new 2.4-inch HD color LCD display. Combined with dedicated knobs, buttons, color-changing footswitch rings and multiple status indicators, the GP-150 gives you clear visual feedback while you're playing and editing.

A dedicated master volume knob provides quick access to overall output level without having to navigate through menus.

Built for Playing & Performing

The GP-150 retains Valeton's familiar dual-footswitch and expression-pedal format, while adding a number of practical upgrades.

The built-in 3000 mAh rechargeable battery provides more than six hours of operation, making the GP-150 an excellent option for portable practice, rehearsals and mobile setups.

The battery can be charged via either the USB-C or 9V DC input, with USB fast charging supported.

The color-changing footswitch rings provide immediate visual feedback, while the external expression pedal and footswitch connections allow you to expand your hands-on control.

Looper & Drum Machine

The GP-150 is more than an effects processor. Its built-in 180-second looper gives you plenty of recording time for practice, songwriting and performance.

The integrated drum machine features over 100 built-in HD drum patterns, providing a convenient backing track for practice and creative sessions.

Powerful Audio & MIDI Connectivity

The GP-150 can also function as a versatile 6-in/4-out USB audio interface, with compatibility across Windows, Mac, iOS and Android.

Bluetooth 5.0 provides wireless audio playback and smartphone connectivity, while USB, Bluetooth and 6.35 mm TRS MIDI control options allow the GP-150 to integrate with a wide range of modern music setups.

The headphone connection uses a 3.5 mm TRRS jack, supporting headsets with microphone functionality — particularly useful for streaming, online lessons and remote sessions.

The right output also features a balanced TRS connection, giving you additional flexibility when connecting directly to mixers, interfaces and other professional audio equipment.

Designed for Real-World Use

Valeton has designed the GP-150 around practical playing requirements, with factory patches reorganized and optimized for quick access to useful tones.

Instead of starting every sound from scratch, you can quickly access a range of tones suited to different artists, genres and musical styles, then customize them to your preference.

The rugged metal chassis, compact format, rechargeable battery and extensive connectivity make the GP-150 equally at home on a pedalboard, in the studio, at rehearsal or on stage.
