Optical Bypass

Here's another alternative to the 3PDT for bypass wiring. It's based on the method VooDoo Lab uses for bypass and uses a optocoupler to achieve true bypass using a DPDT. I've drawn up 2 different layouts for this: a standard perf/PCB layout, as well as another PCB I did in Eagle with the footswitch board mounted. There are extra pads so the compact or the larger DPDT footswitch can be used, as well as an extra pad for the resistor so 1/8th or 1/4th watt can be used.
