We’ve included pads S1 and S2 so you can easily add a switch to
take the clipping diodes out of the circuit. For a stock build you
should place a jumper between these pads - see next page.
C5 should lay flat on the PCB as shown in the cover image.

For a stock build you should place a jumper as shown.
Optional clipping switch
If you take the clipping diodes out of the
circuit you get a completely different crunchy
beast. It’s certainly worth trying the circuit
without them - test it before you add the
S1-S2 jumper. If you want to add a switch to
take them in and out, simply wire up a SPST
or SPDT toggle as shown. SPST will only have
two lugs of course.
