So I have a carbon copy delay that I added an expression out to so when you hit a momentary switch it ramps up the regen. It works well until I put it back in the enclosure. When the pedal and expression plug are both touching the enclosure at the same time the pedal will only do a slap back type thing and the expression does nothing. I'm new to this and I'm not really sure what's going on. Thanks for the help. Here's a pic of it.
