yes, i opened and had a look. i think it's actually one of the slope pedals that makes the distorted noise when the output is too loud. i had that problem before. but if it doesn't bother you and it gives it the oldschool feeling, then it's ok :)
ok thanks kepz its normal i think - the signal goes in the aux-send-delay channel and clipped into the chrusher maybe to much - the idea was a little bit oldschool sound on the delay - the mix knob in crusher is of under 10 percent wet
