Simple, but still seems like one of those super problematic circuits :) This one goes published as unverified for Madferret, who was after a unverified tremolo layout. So. Here you go. Let us know how it works out :)
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.
