When using delay pedals in the loop of my Engl Blackmore (2 x Boss DD-3 delays), the delay repeats sound like they are overloading the signal, and sound distorted and harsh. In the loop in this order is a Boss graphic for solo boost, Rocktron Hush, then the 2 delay pedals. It's worse when you are playing solo's, as there's an annoying fuzzy sort of background noise always present. It's not as apparent on the clean channel, although if you dig in and play hard, the distortion is there. I have the loop signal level set at 50%. On the front pannel, the dirty channel pre amp volume is set at 9 o clock, and the master at 11. I found that if the preamp volume is set higher than the master, the problem is even worse. I've tried to tolerate it, but it's really annoying me now.Somebody help please, as I'm starting to give up on this amp a little, and I'm sure there's a simple explanation as to what I'm doing wrong.
