The GNI XD1 Xtreme Distortion is an analog distortion pedal from GNI Music that also covers fuzz territory. according to RockBoard's PedalPedia, it "can perform from a normal vintage style distortion to an over the top stage melting x-treme megastortion," which puts it in the company of both distortion pedals and fuzz pedals rather than sitting in one narrow lane1.
What it does
The XD1's defining feature is its two adjustable distortion stages. Switching both on at once, via the "x-treme" footswitch, is how the pedal reaches its heaviest sounds, and RockBoard's PedalPedia notes that engaging both stages also raises the output level, which makes the pedal usable as a solo lift as well as a rhythm tone1.
The three-position "mod" switch sets the overall voicing:
| Switch position | Voicing |
|---|---|
| 1 | Vintage classic tone |
| 2 | Modern heavy, scooped mids with more bottom |
| 3 | Modern heavy, scooped mids, more bottom and more presence |
That range means the same pedal can be set as a straightforward vintage-flavored distortion or pushed toward the scooped, bottom-heavy voicings associated with modern heavy styles1.
Power and practical notes
The XD1 runs on 9V DC, center negative, the same supply convention as most modern pedalboards, so it fits a standard power supply setup without adapters1.
The pedal's published dimensions are incomplete: the width is listed as 000.00 mm, a placeholder figure, and depth and height are not listed. Check the physical fit on a crowded board before committing a slot to it1.
