Scenario - multi band gig. Medium sized club. Not much time to change over for set up between bands. First band, three piece - all I can hear are drums and vocals. Moved around the room to see if it was just where I was sitting. Nope. Bad mixing. Second band, six piece, four guitars, three singers - sounded greats We go on next. Pedalboard, Bass, plug in to the House backline GK 800 on a 410. My turn to check levels... waaaaay quiet. Almost couldn’t hear over the club talking conversation level. I tweaked the post knobs on the head and pushed for a little more volume without messing up the board. Sound guy goes “ok, bass...”. I play a little. “Can you turn it down?” The drummer and guitarist laugh. I turned down and literally could hear nothing. I told him I’m going to need more guitar and bass in the monitor. “Ok, bass...turn up a little.” I did and plucked some. He comes up on stage and re-sets the amp to where I could barely hear. I ask him for more in the monitors, and he ignores me. Gig goes on, I’m getting nothing in the monitor. The equivalent of a fry cook spitting on your burger for sending it back. I’m forced to turn up the stage amp Volume. No complaints from the sound guy because he has abandoned the board anyway. Problem is, I didn’t like the sound I was getting. It’s not just volume. The sound was not eq’ed well. Sound guys are going to screw themselves out of a job. Bands are going to be able to convince club owners to let them do the house / stage settings.
