From the post
Pretty cool design; a Rat and a Tubescreamer in one box with a "Contour" control that looks like the Mid control in Wampler Triple Wreck...
...and the requested schematic.
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.
