Here's the situation: I'm home working on refining the setting on my pedal board. Signal flow looks like this: MIA P - Line6 Relay G10 - Polytune 2 mini - Empress Compressor - GK MB800 - two Barefaced One10 cabs Had Crossroads on in the background, Joe Walsh come out and starts Rocky Mountain Way. Got the itch, grabbed my Boss OC-2 (GREAT for RMW) and slapped it in between the compressor and the amp, this is where things went wonky Because I had nowhere to set the pedal while twiddling with it (I'm 6'4" and wasn't about to to go down to the floor to dial in a setting) I set it temporarily on the G10 base (had the transmitter plugged into my P.) When I took the mute off the MB, the whole thing started squealing like a pig, I hit the mute and I could hear a weird low volume pulse coming through the speakers. I was not that loud, had zero problems with any of the system prior to hooking in the OC-2 (after taking the G10 out of the loop, everything including the OC-2 sounded great.) The only thing I can think of was the base (G10 receiver) didn't much like something sitting on top of it, y'know radio signals and all, but the really strange thing is that now it is not working at all. It wouldn't light up, so I tried another wall wart and it lit up but it will not receive a signal. Any ideas? (other than "get a cable, dummy!") Thanks in advance!
