SW1 is an optional SPDT toggle switch to take the diode clipping section in or out of the
circuit. Taking them out gives a crunchier sound and much louder output. To build the
circuit stock without the switch, just leave it out and put a jumper wire between pads S1
and S2. Ignore the two holes above S1 and S3 - these are locator holes if you’re using a
micro-toggle.
