From the post

Another project by Commonsound/4ms.

You can find all info and schematic on their website here.

The original circuit uses a 1M Lin Pot with internal switch for the "Self Oscillation".

I've used a regular pot and an extra SPST switch but you can just use the original if you prefer.

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.
