From the post
Per request. A DIY project posted by Dylan159 at FSB a while back. It is based on Bajaman's EVH OD but tweaked and simplified. Schematic and more info HERE.
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.
