ok, so I tried the different options I had. First I tried going through the FX loop with the send hooked up into the return with nothing plugged in. There was a little pop that wasnt noticable at low volumes, until you crank the amp then you can hear it. Then I tried the delay in loop 2 and I get a loud pop whether the delay is on or off, same with loop 1. Then I also tried the boss tuner in there and the pop was about the same as without anything, so I think its probably the pedal causing it. However, when I have the amp turned on, and the FX loop off, and I plug the send into the input of the pedal, there is a buzz noise just like plugging a guitar into a amp while its on. That didnt seem like it should be happening...what do you guys think I should do?
