Last week while doing my sound check, I had the sound guy ask me to turn up the volume on my handheld mic.
This is a scenario where knowing your gear comes in handy. This was a Shure SM58, which is a very standard microphone and 99% of handheld mics don’t have volume knobs.
I asked the sound guy for clarity, that he was referring to the corded handheld I was holding. He said yes, and repeated that I should turn up the volume on it. I told him I was unaware corded handheld mics had a volume knob and didn’t know how to adjust it, and he’d have to show me. At that point, somehow he magically made the sound go up using only his soundboard.
The whole week ended up being a struggle with this sound company. From them wanting to sound check a band 10 minutes before my show after I had already starting to my “talk up” for crowd building, to them telling me my gear was bad when it ultimately was their snake that had bad inputs.
The moral of the story is to not let anyone push you around, and know your gear, so that you know how it works, why it works and that will usually give you a clue as to why it’s not working when it doesn’t.
