Valeton GP 150 Multi Effects Guitar Processor

BIG SOUNDS in a small box

Since its launch, the Valeton GP‑100 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!

The GP‑150 keeps the compact form factor, but under the hood it’s been supercharged. You can now run up to 12 effect modules and place them in any order you fancy. With more than 200 top‑shelf FX powered by Valeton’s second‑gen HD modelling tech, plus an upgraded 48kHz algorithm sampling rate for pristine sound quality, this thing is built to deliver big, detailed tones. Need control? You’ve got loads. Manipulate up to 6 modules at once, tap your tempos and shape sounds quickly with an array of dedicated buttons and knobs. The GP‑150 also supports SnapTone and full cabinet IR loading, letting you import up to 20 third‑party IRs. And thanks to Valeton’s latest SnapTone tech, you can convert and load NAM (Neural Amp Modeller) files directly into the unit. It even comes stocked with 50 premium files to get you off the line, with space to store up to 100 SnapTones in total.
