our band had the (un?)fortunate pleasure of rocking out again on TV last Friday night. pity y'all weren't there to see it! the TV station has some evil badly shielded power cables running under the floor that wreak havoc with anything that isn't "normal" - ie Rickenbacker pickups. now, talk about "hum", sounded more like a fuzzbox gently feeding back into a phaser pedal. after fiddling around (wasn't cables, the amp, quad or power converter) i had to concede that my darling 4003 was the cause. has anyone else had similar problems? are there shielding tricks to employ here (it's a '98 4003 so methinks it's missing the silly capacitor on the bridge pickup and it *should* be shielded enough), or *gulp* am i looking at the pickups themselves? i do own and have used a noise gate at times, surely this isn't the only option? i mean that'll fix interference at "idle", but with the foot down you can still hear mess in the mix... help?!
