The Fuzz Down Undah is a sub-octave generating CMOS fuzz that yields some heavy square wave monophonic fuzz sounds with a meaty square wave octave below. Select between 1 or 2 octaves below your signal and then dial in the amount of octave you want with the mix knob. Flip the wet switch to kill your dry signal and you’re left with a digital sounding square wave octave down.

Blend in the amount of octave you want with the mix knob and control your signal’s output with the output control.

The octave effect tracks best when played through the neck or bassier pickup of a guitar, play with hot treble tones on your guitar to get the octave to freak out and sputter and jump all over the place, or play multiple notes at a time to yield a cacophony of sound.
