Need footswitch for Duncan 84-50

[JoJoGunn]

Hi,
I'm a new memeber to this forum (although I've read it on occasion). I'm looking for a prgrammable footswitch that goes to the classic Seymour Duncan 84-50 Quadratone all tube amp.
If anyone has one for sale, or knows where I can get one, please contact me at:
songz4us@yahoo.com

Thanks a lot,
Russ
