From the post
There was a bit hassle with this one, but now it's verified and working. Comments on the post are a good read if you're building this. Thanks to Mr. Photon for his amazing work, and special thanks to Pete who verified this.
Mind the notes about the transistors. This is drawn from schematic marked as revision G (The Maestro of Rock version).
More info from DIYSB-thread. Jimi's demo video:
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 Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.

Check before you build · 3 values the reader of this layout was not sure of
- 640K at the left edge, second column: printed clearly, unusual value
- 51pF at the right, below the trimmer: printed clearly, unusual value
- 100pF below the 47pF left of IC1: text overlaps the part outline, read as 100pF
