Hi!
I am modifying a Radial Vienna chorus pedal for a friend with an extra switching output. He wants to switch channel on his Mesa mini rectifiter so when the chorus pedal is on the amp is on the clean channel, and when the chorus is off the amp should switch to the lead channel.
I have made the switching cirucuit on a lab board, it was actually harder than I thought. The foot switches are momentaty, so I had to tap a signal from the bypass LED, which had a different ground point (not 0V) in bypass... But I managed to solve that with a couple of transistor stages and a relay for the switch output.
But here comes the question; how does the Mini Rectifier footswitch input work - should it be open for the clean channel and closed for lead? Or the other way around? I dont have the amp here to test on..
