Hey Kim, cool, glad you found the issue, which pedal was it ?
Well, when I took the Mel9 out of the chain at rehearsal the funny business stopped. But....here I am trying to replicate the problem at home again and coming up empty. This is starting to really get on my tits here. I brought all the pedals home and ran into both the QuadTube and the Crate G60XL with no problems. FFS I can't keep dragging ALL my gear home and back to rehearsal, rinse and repeat twice a week.
Maybe some kind of electrical loop? I have the Crate, Mel9 adaptor, and the Quadtube all plugged into the same power strip here at home.
At rehearsal the Mel9 adaptor is plugged into a power strip that is not shared with my rack gear.
Stan video'd the problem; if he'd send that to me or upload it somewhere I could show you guys what's going on.
