From the post
Time for some doom. Recently traced by evilarsen and an odd fella who likes fuzz. Layout is verified.
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 Dirtbox Layouts. 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
- 845Ω at column 7, rows C-F: printed clearly, unusual value
- Q4 legend reads 2N5008: printed clearly, unusual part number (possibly meant 2N5088, but the legend asks for a low gain NPN, Hfe 50-100)
