How come I didn't get earth loop hum?

    I've been playing for yonks, but never before bothered to run two amps in stereo....

    Anyway, I was in the rehearsal studio and just fancied giving it a go. I didn't use an earth loop hum eliminator, and I figured that there'd be major hum, especially given the state of the wiring in that place (4-way extension leads screwed to the wall, all linked to the one mains outlet). But there was no more hum than is usual for me.

    I took one lead out of my mono DD3 to the practice place's Marshall Valvestate, the other lead out of my analogue Ibanez chorus to the place's fender Roc-Pro.

    So: was it luck, the amps, the fact that the leads were coming from separate pedals, or what? For the record, the dual amp setup sounded much more meaty...

    It could have been a floating earth on one of the mains leads. It could be that you were plugged into 2 seperate phases. It could be any number of things. Not a bad complaint though, NOT having ground loop!:D
