From the post
Still a few Run Off Groove designs I haven't laid out yet, and this is one of them. It's based around the 4049 IC chip and features 2 channels of amp-like distortion. I've laid it out to fit in a 125B with dual footswitches. Bias Q1 to 4.5v and then adjust to taste as usual. More info, schematic and footswitch wiring diagram on the ROG site.
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.
