Check before you build · 3 values the reader of this layout was not sure of
  • Volume and Bass pots: legend prints 'Volume Bass: 250kA' with the '&' missing; read as both A250K
  • DPDT footswitch (wires Switch 2, 3, 5, 6): assumed to be the bypass and left out; it could be an effect control
  • 110K ×3 (cols 4, 10, 11), 240K (col 20), 16K (col 15), 110Ω (col 12), 82nF (col 16): printed clearly, unusual values
