Get to know them!

Driven by second-generation HD digital modeling technology, the Valeton GP-150 is a self-contained sonic solution for any guitarist seeking a grab-and-go rig. This multi-effects processor pedal bolsters your tonal arsenal with over 200 guitar amp, cabinet, and effect models, allowing you to take on even the most eclectic of setlists and sessions with 12 total simultaneous effect blocks. And if you’re already running a third-party stable of sounds, the GP-150 is happy to oblige with 20 user IR slots and the ability to load up NAM (Neutral Amp Modeler) profiles. A brightly colored LCD screen with streamlined controls ensures that tweaking a patch to perfection is as simple as turning the amp style knobs, stomping the LED-equipped footswitches, or letting loose with the onboard expression pedal. And when you’re after a deeper level of tone-shaping control, the GP-150 also features MIDI functionality and an in-depth editing app accessible via desktop or your mobile device. Looking to lay down a new track? The GP-150’s 6-in/4-out audio interface has you covered. You also get a robust assortment of tools to optimize your practice sessions, including audio streaming over Bluetooth, 100 drum grooves, a 180-second looper, and flexible I/O with footswitch/expression pedal options. It’s finished off with an internal battery that delivers up to six hours of uptime. Compact, accessible, and all-encompassing in scope, the GP-150 sets the benchmark for mid-sized modeler pedals everywhere.

Capture music's most iconic tones with 200+ models

Sweetwater's tone chasers can confirm that the Valeton GP-150 puts the most iconic sounds in music history at your command, featuring over 200 studio-ready amps, lifelike cab sims, and legendary stompbox effects. These models leverage Valeton’s second-generation HD digital modeling technology to deliver the most authentic, organic, and responsive tones possible, with 12 simultaneous effect modules on tap. Blocks can be arranged in any order you wish, allowing you to craft everything from no-nonsense rock ’n’ roll crunch tones to effect-laden psychedelia in a matter of moments. In addition, the GP-150 also boasts the ability to load up NAM profiles and up to 20 third-party IRs from your personal collection.

Performance-focused workflow

The GP-150’s mid-sized, dual-footswitch form factor lends itself to straightforward tone sculpting, featuring a large color LCD screen that’s controlled via a collection of knobs, buttons, and the two LED-equipped footswitches. From exacting parameter adjustments to exploring the GP-150’s myriad preset patches, this player-friendly control scheme is further aided by a built-in expression pedal for dynamic mid-song control over your chosen parameters.

Armed with an array of utility features

In addition to its studio-grade collection of tones, the GP-150 comes equipped with a vast variety of utility features to satisfy all your practice, recording, and performance needs. Looking to record a fresh riff? Plug the GP-150 into your desktop or phone to access its 6-in/4-out audio interface capabilities. Need to practice a tricky track before the big gig? A 180-second looper, 100 onboard drum patterns, Bluetooth audio streaming, and a headphone jack help you make the most out of your woodshedding sessions. And for those ceaseless tone chasers who demand full control over every facet of their tone, a companion app for both mobile and desktop makes it easy to sculpt every minute element of your sound.
