I'm currently playing in a theatre pit; yesterday was load in. It's a 16 person group with two keyboards and me as the only amplified instruments. One keyboard amp is side-washed; my amp is facing me, about 4 feet away on an angle. The second keyboard amp is also diagonal. The pit area itself is about 8' deep and runs the length of the stage. The back wall is cement that about 6' up, curves out. I'm using my GK MB-150S amp (1x12, 100w or so). When I loaded in yesterday, the sound guy refused to run a DI, citing that the bass carries really well in the theatre. I was surprised they didn't just run it and have the option of not needing it, but didn't say anything. Three songs into it, the sound guy says that the bass needs to be turned down. I politely ask if it's me or one of the keyboard players. After the keyboardist in question plays a couple notes, the sound guy says it's him. This keeps happening over the course of rehearsal, to the point where I intentionally don't play a song to prove that it isn't me. We're planning on sidewashing the other two amps, but wanted to know if I'm missing something here that we can try to do to help the sound guy get a good mix. I'm still not convinced that this sound guy knows what he's doing anyway; given the mic volumes yesterday and amount of feedback they were getting on things, I'm not so sure it's entirely us. But, I'm willing to give it a shot and see if we can control ourselves a little more. Any help or ideas to try would be appreciated.
