Found this circuit from the DEFX files and thought this to be quite interesting. Discontinued circuit with noise for days. From the source:
The GREEN
MONSTER septic fuzz (GM2)is an effect
pedal to create a septic distortion.
Characterized by a dirty, broken and rotten sound. Bad handling!
GREEN MONSTER is back with four knobs! There is an easy to use sound
which the first GREEN MONSTER (ultra fuzz) was never able to create,
but the sound is still putrifying! Genuine septic sound can be found
here!
First one is close to the original...
