Last year our 3 piece band played a live gig in a large curling rink with a few hundred people in the audience.The soundman was freaking out because I was playing my bass strings too close to the pickups and "could blow a speaker".I had direct input and was playing through the house system. I've played through large,outdoor systems and have had no problems. I use a '72 Fender Jazz bass with two non-active (original) pickups.I keep my volume and treble-bass controls at max to get a full sound.Should I change my technique? Was the bass set up too bright on the house system?
