This is a five-knob fuzz using two new old-stock sixties germanium transistors. The circuit is not modeled after any classic fuzz design, but should have been around when Leary was still lucid.

This pedal is so dangerous that we are sure we will be getting a lot of complaint emails that people have blown up their amps using it. So let's just start this off by saying WE WARNED YOU TO BE CAREFUL.

Designed for bass but a favorite for guitar, this incredibly sub-frequency-preserving unit will hold onto the lowest lows like no fuzz ever heard before, and features a gentle gate (pinch knob) for silencing your instrument between notes or phrases, and has an eq control that smoothly selects between no bass and more treble.

The circuit uses a combination of germanium diode and transistor fuzz generation and a ring modulator to turn simple chords into nutso note combinations and complex chords into incredible noise...and makes solos soar impossibly high.
