From the post

MTK traced this pedal and sent gutshots and component values to AlexS who sent them to me to make a schematic and a proper layout with all components on the board. Still, there is some offboard wiring to do since it is two circuits in one enclosure.

So what is it? Essentially an Electra Distortion going into a Meathead with an input/output selector switch. Once again, thanks to MTK for tracing this!

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.
