Iron Butterfly Fuzz Wah
Based on the Iron Butterfly Fuzz Wah
From the post
Not much info on this one, not even who actually made it. Found the schematic years ago over at DIYSB where it was reversed with the help of none other than dino. Figured I'd tale a shot at a vero since I did so many other wahs.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
