I did this layout based on Dirk's schematic here. Now 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 Tagboard Effects. 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
- 110R at the right edge of the board: printed clearly, unusual value
- Unlabelled blue two-lug part off board at the right (green wire to the board, other lug to ground): read as an SPST toggle, but it could be the rate LED; the drawing gives no name or type
