Building Expression Pedal Help!

[posse32]

Hey there, new to the board!

   It looks great here, I love it! Building your own stompboxes is great!

  I was just have some troubles and was wondering if anyone could possibly or be willing to help. I have a volume pedal from an old electric organ and I was looking to convert it to an expression pedal for another pedal that I have. Any help in this area? Thanks!

You'll first need to figure out how the thing you want to control is wired. There many different expression schemes. Some are voltage dividers diving audio or a control voltage; these need 3 contacts. Others are a varying resistance; these need only 2 contacts. But you also need to determine how the expression jack is wired. If you tell  us what you're trying to control we can possibly help figure it out.
