The Valeton GP-50 is a dual-footswitch pedal-format multi-effects processor and SnapTone & IR loader: a single unit that carries more than 100 effects based on advanced modeling, loads impulse responses and converted Neural Amp Modeler captures, and can run on its own built-in battery. It is the larger sibling of the Valeton GP-5, a compact multi-effects unit that Pedal of the Day described as offering advanced signal routing, a large set of effects, and impulse response loading12. The GP-50 was released in 2025, building on what that review called an already classic multi-dimensional piece of gear from earlier that year2.
What the GP-50 does
At its core the GP-50 is two things in one box. First, it is a multi-effects processor: Pedal of the Day counts more than 100 high quality effects based on advanced modeling, covering the ground a player would otherwise fill with individual multi-effects pedals2. Second, it is an IR loader built around Valeton's SnapTone technology. SnapTone allows you to load converted NAM (Neural Amp Modeler) files directly into the unit, so amp captures made by the NAM community, once converted, can live on the pedal itself45.
Out of the box, Valeton includes five factory SnapTone PEDAL files, each modeled on a known drive or distortion circuit3:
- 14 DST, modeled on the Fortin Natas
- Force OCD, modeled on the Fulltone OCD V3 in HP Mode
- Revolt DST, modeled on the Suhr Riot
- SweetDrive, modeled on the Mad Professor Sweet Honey
- FlagmanDST, modeled on the Friedman BE-OD
Those five cover a spread of gain styles, from the high-gain Natas to the lower-gain Sweet Honey, so the pedal has usable amp and drive tones before you load anything of your own3.
Presets, battery and connectivity
The GP-50 ships with 55 factory presets and 45 user slots, so there is room to keep the stock sounds and still build a personal bank2. Power is a standout for a unit of this type: it comes loaded with a 1450 mAh rechargeable battery, and Guitar Pedal X likewise lists built-in battery power among its supply options23.
A built-in rechargeable battery means the GP-50 can be played without a power supply connected, which sets it apart from most pedalboard multi-effects units that need mains or a dedicated supply at all times.
On the back panel, connectivity is stereo and MIDI capable. The unit has dual 1/4-inch TS unbalanced stereo output jacks, and Valeton states that it supports USB MIDI and features dual 1/8-inch TRS jacks for MIDI input and thru functionality1. Pedal of the Day notes that MIDI support opens even more control options, which matters if you want the GP-50 to sit under the control of a larger switching setup2.
How it compares to the GP-5
The GP-50 is explicitly a step up from the GP-5. Pedal of the Day describes it as building on the small and beloved GP-5 Multi-FX Processor and pushing the boundaries with more power and more flexibility2. The GP-5 itself is a multi-effects processor and IR loader with advanced signal routing and a large effects set4, and it carries the same SnapTone approach: Valeton's product page for the GP-5 introduces the same technology for loading converted NAM files directly5. In practice, the GP-50 adds the dual-footswitch format, expanded connectivity and battery power on top of that shared foundation.
What reviewers said
Pedal of the Day's verdict on the GP-50 was warm:
"Valeton has come through with yet another rousing multi-effect unit that does, well, everything."
That review positions the GP-50 as a do-everything unit in the same family as Valeton's larger processors, such as the GP-200, while keeping the pedal format and battery power that the bigger floor units do not have23.

Questions
Does the Valeton GP-50 run on a battery?
Yes. Pedal of the Day notes that the GP-50 comes loaded with a 1450 mAh rechargeable battery, and Guitar Pedal X lists built-in battery power among its supply options. That means the unit can run without a power supply connected, which is unusual for a multi-effects processor and useful for practice away from an outlet.
How many presets does the Valeton GP-50 have?
The GP-50 ships with 55 factory presets and 45 user preset slots, according to Pedal of the Day's review. The factory presets give you a starting point across the unit's effects, while the user slots are where you store your own edited sounds.
What is SnapTone on a Valeton pedal?
SnapTone is Valeton's technology for loading converted NAM (Neural Amp Modeler) files directly into the unit, as described on Valeton's own product pages. The GP-50 also ships with factory SnapTone PEDAL files, including models based on the Fortin Natas, Fulltone OCD V3, Suhr Riot, Mad Professor Sweet Honey and Friedman BE-OD.
Can the GP-50 load Neural Amp Modeler files?
Yes, in converted form. Valeton's SnapTone technology allows you to load converted NAM (Neural Amp Modeler) files directly into the unit. You cannot drop in raw NAM captures; they go through Valeton's conversion first, and the pedal also carries a set of factory SnapTone pedal models out of the box.
Does the Valeton GP-50 work with MIDI?
Yes. Valeton's product page says the GP-50 supports USB MIDI and features dual 1/8-inch TRS jacks for MIDI input and thru functionality. Pedal of the Day adds that MIDI support opens even more control options, so the unit can sit in a larger rig and be switched from elsewhere.
Is the Valeton GP-50 stereo?
Yes. The GP-50 has stereo connectivity, built around dual 1/4-inch TS unbalanced stereo output jacks, as listed by both Valeton and Guitar Pedal X. Running both jacks gives you a true stereo output path for effects that benefit from it, such as delays and modulations.
