From the post
Gotten a lot of requests for this one. I've put it off because the schematic that's out there isn't exactly straight forward, not to mention it's 7 pots, 2 switches, 3 ICs... You get the idea. Anyway, I wanted to keep this 1590BB friendly, so all the pots are board mounted... except one (Blend). Six out of seven isn't bad, I reckon. haha
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.

Check before you build · 2 values the reader of this layout was not sure of
- 32nF at the bottom of the board left of the 15K: printed clearly, unusual value (33nF would be the usual one)
- regulator beside the upper 100uF: no value on the populated board, 7805 taken from the wiring diagram
