Nope Bill, I have a special cable coming out of my effects sent that has 4 plugs on it, 2 go into repeater (unfortunately Mono-ising the input) and the other 2 go into the 2 EDPs. Noy exactly a Y cable, more like a WV cable!
this sounds really suspect to me , noise -wise do you mean you send to one looper, then another and then another before returning to the mixer, for resampling? Clarify if you can a bit more.
