I just got a mod 50 and love the amp. But I am in a cover band and use a lot of effects and I have not been able to get the effect loops to work without sucking all the tone away. I put my delay, chorus and flanger in the series loop and it gets muddy sounding, I tried the tweaking the manual said use and it did't help. I like way the pararel loop sounds but I can't turn the effects up enough to work with songs by the cure or U2. By the way I use a Boss DD3, Boss CE-2 and Boss Hi-band Flanger. Anyone have any tips?
