From the post
Just saw this schem posted in the forum and thought it looked like a pretty cool effect. The original has a funky LED setup and uses the 3rd pole of the 3PDT to cut the 9V connection to the whole circuit. I have drawn this layout to fit our normal offboard wiring.
Info from manufacturer:
The "RATTLE CROW RESTIVE FILTER" (RC) is an effect pedal in which the filter is affected according to the size of the input.
Characterized by a wild and sorrowful tone.
The RC is a kind of auto wah, but it has hysterical and distorted qualities, a broken auto wah sound.
