Thank you for responding!
I would like the unit built for me, or at least the board ready for me to wire up switches and connections and put in an enclosure. size is important as i would like this to fit in a standard stomp switch enclosure (2.5x4.375x1 approximately). the actual switch will be a purchased momentary on or off (whatever is needed, though I prefer an NO state) that i will get. the resistance is connected with just 2 wires. it is probably wired to ground since the pedal is using a TS 1/4" cable with the tip and sleeve carrying the wires (sleeves go to ground almost always I believe).
