I was working on a few Devi Ever clones and wanted to make 1 pedal that can be shaped into 3 different pedals. Devi is know for using 1 PCB for 3 or 4 pedals with just a few component changes. I wanted a way to wire a switch to change between 3 different capacitors or 3 different resistors. Here is what I have found.

I laid this out in DIYLC to give an example. The switch is a DPDT on-on-on Toggle Switch

You will be able to do the same thing with resistors. Just replace C1-C3 with the needed resistor values.
