The Brokeman Fuzz is a silicon fuzz face style circuit, with a twist. The break switch allows for crazy and unique sounds like squeals controlled by your guitars volume controls, or glitchy synth-like octave down effects.
This fuzz is also very versatile just as a regular Fuzz Face, with adjustable bias, allowing for everything from super velcro-ish fuzz to gated 'dying battery' sounds. It also cleans up really well when rolling the volume down on your guitar.
This pedal should be first in the chain, or at least before any buffered pedals.
