The Valeton GP-100VT is a compact digital modeling multi-effects processor, described by Valeton as "a multi-effects processor based on the acclaimed GP-100 design"1. It puts amp modeling, cabinet simulation and a range of effects in one floor unit: Pedal of the Day's review counts over 50 effects covering dynamic EQ, overdrive, modulation, delay and reverb, plus 40 IR cabinet models2. It sits in the wider family of multi-effects pedals and is a variant of the Valeton GP-1002.
What it does
Valeton says the GP-100VT carries the company's HD digital modeling system, "delivering you organic living tone"1. In practice that means one unit handles the jobs a pedalboard would otherwise split across separate overdrive, modulation, delay and reverb pedals, with amp and cabinet modeling on top. The 40 IR cabinet models noted by Pedal of the Day let the unit imitate miked cabinets, which matters if you play through headphones, a computer interface or a flat full-range amp rather than a traditional guitar cabinet2.
Presets and patch mode
The GP-100VT holds 198 presets, split evenly between 99 user slots you can overwrite and 99 factory slots, which Valeton describes as "fine tuned by skilled professional musicians"1. Two footswitch modes change how the switches behave:
- Patch mode: tap to toggle between patches, stepping through whole setups one at a time1
- Stomp mode: tap to turn individual effects on and off, in the manner of separate pedals3
Patch mode suits players who change sound between songs; stomp mode suits players who want the unit to behave like a row of individual pedals31.
GP-100VT and GP-100
The two units share their core. The GP-100 is described by Valeton as "an affordable compact multi-effects processor" with the same HD digital modeling system, the same 198 presets (99 user plus 99 factory) and 40 high quality factory cab IRs3. The GP-100VT is built on that design and adds a distinctive look: Valeton says that "going through 6 degrees of complex production processes, we were able to create this unique and eye-catching 'jewel violet'" finish1.
Connections and power
The enclosure is what Valeton calls a "full metal rock solid chassis ready for wear and tear", measuring 198mm wide by 134mm deep by 28mm high and weighing 800g1.

Questions
What is the difference between the Valeton GP-100VT and the GP-100?
The GP-100VT is built on the GP-100 design, so the two share the same core: an HD digital modeling system, 198 presets split between 99 user and 99 factory slots, and 40 factory cabinet IRs. The VT version sets itself apart with a distinctive "jewel violet" finish that Valeton says was created through six degrees of complex production processes. Pedal of the Day lists the GP-100VT as a variant of the GP-100.
Does the Valeton GP-100VT have a USB connection?
Yes. The GP-100VT has a USB 2.0 Type-B port, according to Valeton's product page. That is the unit's computer connection alongside its 1/4-inch guitar input, left and right 1/4-inch outputs, an auxiliary input and a headphone output.
What power supply does the GP-100VT need?
Valeton specifies DC 9V at 500mA for the GP-100VT. That current draw is higher than many single pedals need, so it is worth checking what your power supply delivers before sharing a daisy-chain output with other pedals.
Does the GP-100VT have cabinet simulation?
Yes. Pedal of the Day's review notes 40 IR cabinet models on the GP-100VT. IR, or impulse response, cabinet models let the unit imitate the sound of miked guitar and bass cabinets, which is useful for playing through headphones, an audio interface or a flat full-range setup.
Is the GP-100VT stereo?
It can run in stereo. Valeton lists left and right 1/4-inch unbalanced outputs, so the unit can feed two channels of an amp setup or audio interface. There is also a 1/8-inch stereo headphone output and a 1/8-inch stereo auxiliary input.
