From the post

Now this one is quite a mystery to me. Analogguru's schematic matches the gutshot at the effectsdatabase, yet the demo suggests something quite different from your average Dist+/250 clone. Schematic states that the pot values are guesses, but there are clone build reports around the web.. So. However it may be. Here it is. The Almighty DeArmond Square Wave Distortion Generator.

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.
