The Olsen Interface Warspit Distortion is a distortion pedal built around a spread of fuzz voices. Pedal of the Day, reviewing it in September 2021, described it as producing "a nice spectrum of distortion gooiness that oozes from your amplifier", placing it closer to the fuzz end of the overdrive family than to a straight clipping distortion1.
Controls
The Warspit's faceplate carries no labels, which is part of its character. Pedal of the Day counted seven knobs, five switches and two footswitches, and called it "an experimenter's dream box" on that basis1.
| Control | What it does |
|---|---|
| Volume | Overall level, one of the golden knobs giving a wide range of sounds and tones1 |
| Fuzz (x3) | Three fuzz knobs among the golden knobs1 |
| Fuzz Noise (x2) | Two fuzz noise knobs among the golden knobs1 |
| Cut switches (x2) | Take Fuzz 1 or Fuzz 2 out of the signal, respectively, and raise the volume a bit1 |
| Momentary switch | Toggles back and forth between the two tone settings, giving either a burst of boost or a quick cut1 |
| Yellow switch | Controls the overall tone and momentary switching: one setting is quieter and more gated, the other louder and more open1 |
The two Cut switches and the Momentary switch work together: with a Cut switch dropping one of the fuzz voices, the Momentary switch lets you flip between the two tone settings on the fly for a temporary lift or dip1.
What reviewers said
Pedal of the Day's review is the published verdict on record. Beyond the "experimenter's dream box" line, the reviewer said the pedal's wide range of sounds puts big tones into the sound, and added that they were fully on board with Olsen Interface's direction overall1.

Questions
How many footswitches does the Olsen Interface Warspit have?
The Warspit Distortion has two footswitches. Pedal of the Day described the whole layout, with no labels, seven knobs, five switches and two stomps, as an experimenter's dream box, reflecting how much of the pedal's range comes from combining its controls rather than reading them.
What do the Cut switches do on the Warspit Distortion?
The Warspit has two Cut toggle switches. According to Pedal of the Day, each one takes Fuzz 1 or Fuzz 2 out of the signal, respectively, and raises the volume a bit, letting you drop a fuzz voice while pushing the level up.
What does the yellow switch do on the Olsen Interface Warspit?
The yellow switch controls the overall tone and momentary switching. One setting is quieter and more gated, while the other is louder and more open, so it shapes the pedal's overall character between two distinct voicings.
Who makes the Warspit Distortion?
The Warspit Distortion is made by Olsen Interface, a builder of fuzz and distortion pedals. Pedal of the Day reviewed it in September 2021 and said it was fully on board with the company's direction overall.
