From the post
Here's a pretty cool bass distortion based on the RAT. The normal filter section on a RAT is replaced with a passive baxandall network. It was traced by FSB member p.eat and the schematic I based this layout from was drawn by johnk.
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 Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.
