From the post
I think Mark would have squeezed this in a bit more compact size, but i got it "down" to 21x29. So super brave folk may aim for 1590B, but rest of us may want to give this a go with 125B or 1590BB instead. Layout is based on a schematic which was provided with the original units, along with stickers and other paperwork. Circuit has some similarities with Boss HM-2 Heavy Metal as the youtube demo below suggests. Sounds pretty mean.
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
- 47uF drawn as a red box (film) capacitor beside Q1, top left: printed clearly as 47uF, unusual for that body, may be meant as 47nF
- D2-D4 and D7-D8: legend prints 1N4147, printed clearly, unusual part (possibly 1N4148)
- 200Ω resistor at the left edge below Q2: printed clearly, unusual value
