Hey all, The place my cover band has been practicing at has one problem: every amp seems to buzz there! It's this kinda 'bzz' that goes on when not playing. I first freaked out as I thought my amp might be going, but then I noticed that PA and guitar amps give out similar hiss. The problem got ever worse when I brought few guys from another band to try out couple songs, we plugged into couple of Ampeg guitar combos and coulden't play because of the huge amount of very loud buzz we suddenly got from the amps each time the other guitarist played through his distortion pedal! We had to plug off all their pedals (Ibanez Fuzz and Korg multi-effect at the time) and go straight into amps without distortion, there was only slight background hiss after that. I think the problem might be either the flouricent lights the place has, or the power outlet - we have to take power out from single wall plug and have half a dozen or so of those powerchain-thingies and lots of powercords going on the floor. Any thoughts how to improve the situation, anyone?
