From the post
Almost a year ago I laid out the silicon version of the classic FuzzRite. Lately though, I decided to redo it after some discussion with Gabriel Monteiro over the 22k resistor. To see that discussion check out the first layout page for this circuit. Our discussion (which in all honesty was mostly a bunch of breadboarding on his part, thanks buddy!) had nothing to do with redoing the layout, but it made me look at the old layout enough that I wanted to redo it, and when I couldn't find my original DIYLC file for it, I had the perfect excuse. So here's the FuzzRite again. This time much more orderly 1590a friendly.
I also redrew the schematic to get my head around it a little better and to also number the pot lugs (which is lacking in most schems and seemed to be a source of some confusion on my part when I originally drew the circuit up).
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.
