I play in a bluegrass band where we have switched from using direct boxes for each instrument to using a pair of shure ksm 27s mics in the more traditional bluegrass style when we play live shows. We have one set higher for vocals, fiddle and harp to stand around and one lower for the banjo, mando and guitar player to stand around. I, as the bass player, have been plugging in to my little gk to avoid any feedback from having a third mic on stage. Since we are never too loud, I'd like to start using a mic for my bass as well and am torn between two different choices: should I get a third ksm 27 so I have a "matched set" of mics or should I get a beta 52a that is more geared towards bass frequency? When we recorded our album, the sound guy used the 52a but I'm not sure what would be the best set up for live sound. Any suggestions would be appreciated.
