Just a bit of fun.....Before you soundcheck the instruments, do you play recorded music through your PA to EQ the system? If so what song do you use and why? My Guitarist uses "Weather with you" by Crowded house. He says it's because he knows it very well and it's mellow enough not to freak out any patrons who are already in the room. I use "Seven" by Prince for the same reason, except I'm more concerned about freaking our management than patrons. Plus it's got a long intro which is vocal harmonies only. It lets me get the mids right before the band kicks in with the other frequencies. Your turn.
