Hi all. I put my SA Collider delay/reverb pedal in the effects loop of my AA3 in SERIES mode. When I cranked the mix of the pedal all the way up, There seems to be a lot of dry signal making its way thru the loop (which is what I would expect from the loop set to PARALLEL mode). If I put the pedal in front of the AA, the mix knob behaves as I typically expect (100%mix = 0% dry guitar). Note that I am ran the pedal stereo and mono back into the return with similar results. Is there a setting I am missing? I am new to the loop in the AA. Thanks!
