Valeton GP-5

The Valeton GP-5 is a multi-effects processor, SnapTone amp modeler and IR loader from Valeton, built into a tiny mini-pedal format¹. It packs over 100 high-definition modeled effects, 50 factory presets and room for 50 user patches into a metal casing measuring 93.5mm wide, 42mm deep and 52mm high, weighing 237g². Valeton positions it as the latest evolution in its GP series, and it launched at $79²³.

For players, the appeal is size. As Pedal of the Day put it, many multi-effects units are too big for a neat and tidy pedalboard, while the GP-5 provides more options than you'll know what to do with in a package about as small as it can be⁴. Bass Musician Magazine found it aimed at practice, travel and compact live setups: a dependable backup rig taking up minimal space rather than a replacement for large floor units⁵.

Signal chain: ten fixed blocks

The GP-5's signal chain is made up of 10 blocks, with up to 9 active at once, that cannot be moved around and are preset to different effect types³. Guitar World lists the block types as Gate, Pre, Dist, SnapTone (NAM), Amp, Cab, EQ, Mod, Delay, and Reverb³. The Pre block holds a selection of compressors, boosts, pitch, and auto-wah effects³.

The amp models cover a wide range of styles. Sound On Sound's reviewer found amps inspired by classic clean platforms by Fender, crunchy options for a selection of Vox or classic Marshall-style tones, and higher-gain rock and metal amp styles including modern Marshall, Mesa, Peavey and others¹.

The SnapTone block is the GP-5's route into NAM (Neural Amp Modeler) captures, though Guitar.com notes it currently uses the more limited SnapTone versions of NAM captures⁶. Guitar Pedal X compared it directly against the IK Multimedia TONEX One, calling it a formidable challenger to that unit⁷.

Editing is where the GP-5 asks something of the player. All patch creation, signal-chain configuration and IR management are handled through the Valeton app, not on the pedal⁵. The pedal itself offers two bypass modes, analog and digital⁷.

The footswitch and its four modes

The GP-5 is a one-footswitch package³. That single footswitch features a smart LED ring with user-definable functions, and Valeton lists four usage modes²:

• Patch: preset switching²
• Songlist: stepping through an ordered set of patches²
• Stomp CTL: switching individual effect blocks on and off²
• Tuner (Bypass): tuner and bypass functions²

Morningstar's guide to controlling the GP-5 over MIDI notes the trade-off plainly: the GP-5 has a lot going for it, but adequate visual feedback and footswitches are not among those things⁸. Players who want more switching and onboard editing can look at the larger GP-50, which Bass Musician Magazine judged a clear evolution of the GP-5 with onboard editing, dual footswitches, expanded I/O and battery power.

Power, battery and connections

Power comes from two routes: a DC 9V center-negative supply or USB 5V, drawing 100mA on DC or 190mA on USB². On top of that, the GP-5 has an internal rechargeable battery, which Bass Musician Magazine found adds a level of freedom that many larger units cannot match, allowing bassists to practice without mains power⁵.

Connections are minimal: one 1/4" unbalanced TS input, a 1/4" unbalanced stereo TRS output compatible with headphones, and a USB 2.0 Type-C port²³. The TRS output can feed a stereo mixer or PA as well as headphones¹. Input impedance is 1M Ohms, output impedance 100 Ohms, and signal-to-noise ratio is 100dB².

MIDI control over USB

The GP-5 receives MIDI via its USB-C port, on MIDI Channel 1 by default, and that channel is currently not changeable⁸. It responds to Control Change (CC) messages for preset recall, and preset numbers correspond directly with CC#0 and the corresponding CC value: CC#0 with value 1 recalls preset 1⁸. It also receives CC messages to bypass or engage individual effect blocks, where the CC number identifies the block and the value 0 means bypass and 127 means engage⁸. The blocks that can be toggled this way include NR, preamp, distortion, modulation, delay, reverb and EQ⁸.

Selected CC assignments from the published MIDI CC list⁹:

The USB-C port also carries 2-in/2-out USB audio, compatible with Windows, Mac, iOS and Android systems², at a 44.1 kHz sample rate and 16-bit depth⁷.

Firmware and software

Valeton's support site lists firmware V1.0.6 for the GP-5, compatible with mobile phone software v1.0.4, a 1.05 MB download updated on 27-11-2025¹⁰. An earlier V1.0.3 firmware was compatible with computer software v1.0.7 and mobile software v1.0.0². Editing and IR management happen through the Valeton app over USB or the pedal's Bluetooth 5.0 Dual-Mode connection (BLE and audio)²⁵.

What reviewers said

Guitar World's reviewer rated the build robust and surprisingly premium feeling for the price, with the exception of the screen, giving the build quality section four and a half stars out of five³.

Bass Musician Magazine, reviewing it for bass players, found it a streamlined solution that works equally well for practice, travel and compact live setups, and a dependable backup rig taking up minimal space⁵. Sound On Sound's reviewer noted Valeton might not have quite the same profile as the likes of Line 6, Fractal, Neural DSP or Kemper, but found the amp coverage broad, from Fender-style cleans through Vox and classic Marshall crunch to modern high-gain designs¹.
