From the vendor
A small custom run by D*A*M of a modified Zonk Machine circuit, adding an input cap blend (the Filter control) to the three-transistor germanium fuzz. The post has no schematic, only Sinner's layout.
Schematic
The schematic is in the post. Open it at Revolution Deux. No KiCad fragment has been drawn for this circuit yet.

Check before you build · 2 values the reader of this schematic was not sure of
- Read from a vero layout, not a schematic; part roles are not certain and the numbering follows the board left to right.
- Two parts drawn as small circles (1M and 15k) are read as vertically mounted resistors.
