I've posted a couple of circuit diagrams in the Files section. Marshall sent me pdfs of the circuits for the foot pedals for the TSL and AVT amplifiers. I'm confident that there's no way that I would be able to configure the relay contacts on the FCB1010 to change channels. However, there may be some electrical whizzes out there that can, so good luck!!

We do have a couple of electrical engineers on the group, so... -- Mike Whitaker
