From the post
Traced by TOFO. This is a layout for the early big box version with three footswitches. It is based on the russian Big Muff but with more gain, reversed tonestack tone bypass switch, switchable and tunable feedback loop and a diode selector switch for the second clipping stage.
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 Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
