We've been playing in this one club for years and it is driving me crazy. Every place else that we play my rigs have been as quiet as you could expect, with just the normal amount of hiss when you kick on the high gain channel. At the club last night, it was again as expected, as though a REALLY large swarm of bees was let loose if I switched to the gain channel. As long as I was playing it was tolerable, but it was impossible to let a note fade out as the bees would rush in. I've tried taking my pedalboard out and going direct, different cables, "noiseless" pups, switching guitars and amps and nothing seems to help. Would a power conditioner help, or is the wiring in the club so bad that there is nothing to be done? Basically everything has to be plugged into the same circuit, and there is enough neon in there to the point of distraction. We get great crowds and LOVE playing there because of that, and they don't seem to notice any problem.
