PCB FOR DIY GUITAR EFFECTS

Size of Board: 52mm WIDE x 41mm HEIGHT (1590B Box Ok!)
The slashed part are changes needed to build RC.

For AC, use 2 diodes in RV and 1 in  FW clipper group.
For RC, use 3 diodes in both RV and FW clipper group.

Transistor in the original unit is 2SC1815 (view from top, left to right = ECB)

Size of  Board: 56mm Wide x 36mm Height (1590B Box Ok!)

This is really classic. No mod, no change.
(except some additional pad / components for the modern 3PDT bypass)

I draw this base on popular demand however, i will not share the PCB trace for the time being. Sorry for all inconvenience.
