And by the way, why do bluegrass bands make the bass player (upright) stand in the back? Everybody else gets to be up front whether they sing or not, and there's the bass player shoved into the background. Is it a sound/microphone thing? Am I the only one who gets pissed about this?
The bass notes throw such a long sound wave the instrument needs to be further back for the other musicians to hear a fully developed note, and the bass can still bleed into the microphone.
I was in a band that was on a four-band bill, and all the other bass players (bluegrassers) crowded the mic (and could not be heard front of house). I stood as far back on stage as I could get (I have a heavy-handed attack) and pulled aside a bit of the backdrop to expose the brick wall behind, so I had both the f-hole sound and the rebound off the wall going for me. After our set I heard the sound guys, who were set up two thirds of the way back in the hall, say I was so loud I didn't need a mic. I was playing a horribly set up Kay M-1.
