Since its launch, the Valeton GP-150 has been winning over players left, right and centre — quickly becoming Valeton’s go-to hero for incredible value and killer tones. And now, they’re back with an upgrade that kicks things up several notches: the Valeton GP-150. It’s a digital multi-effects processor that takes everything you loved about the original and cranks it up to eleven!
GP-150 is powered entirely by Valeton’s second-generation HD digital modeling technology. Built-in 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.
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.
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.
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.
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.
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.
