I'm going to rewire the volume pedal that I already had from my Yamaha PS6100. It works backward on the Solton X1. Usually there are two or three wires going to the potentiometer. I will have to reverse the wires. If there are just two wires you have to switch them. Please notice that two posts on the potentiometer are usually connected together when two wires are used. If there are three leave the one in the middle and switch the two ends.

On the damper pedal they are usually a momentary on or a momentary off type of switch. These can't just be rewired. They are built to work in a specific way and can't be rewired. I hope this helps.
