Oldghm posted:A good exercise for a singer is to take two or three different mics, set them up, all at the same time, with EQ flat and all other controls set to the same value and see which one pleases them the most. This will give an indication of how the mic colors the vocal, how the mic responds to input in direct comparison with other mics, which influences how we feel when we sing.
I wanted to piggy back on this and mention that most of the larger mic manufacturers have "demo packs" they can send you to try before you buy. When I was looking for a vocal mic for my wife for a vocal group she was singing with, Sennheiser sent us 4 different mics to try out in actual live situations, rather than saying "Check One, Two" in a Guitar Center. When we were done, we sent them back and bought the one we liked.
