Thanks Tom. The Roland has 3 wires as I remember, I am going to follow your instructions and I'll let you know.The Korg volume pedal I have works with the Solton but the Roland is all metal and better quality. When I had the I30, Korg gave you the option to reverse polarity for the damper pedal, Solton does not have this feature. I'm waiting for my SD1, when it arrives I'll do the rewire.
Thanks
John C.
