The Backpfeifengesicht is a synthie style Fuzz. It takes the input signal from your instrument, amplifies it with a 386-type amplifier IC, and uses this to retrigger a free-running oscillator made with a 555 counter IC. In addition, the input signal's envelope can sweep the frequency of the oscillator. The end result is a buzzsaw synthy distortion, capable of octave effects and faux-resonant filter sounds.
