I’d like a schematic for a footswitch for the OD200.

To control the two Drive channels, a 2-button footswitch wired to a TRS cable controls each of the two drive channels by grounding its respective conductor. This is most readily accomplished with a “British style” two-button footswitch. When the plug is inserted, the front-panel pushbuttons are disabled and the footswitch takes over. There is a link below where you can find them. There are other companies that sell them as well.
