bluegrass players often use one mike to amplify
the entire band. there are some sensitive ones
these days which can carry the sound from a whole
stage-full of players..this necessitates a different
sort of choreography in order to dance around the mike
so that players can take solos, be heard, etc. this
adds an aspect of communication betweer band members
which takes some training...but frees up the musicians
to be able to be more mobile on stage, too. The sound
balance is established by position in relationship
to the microphone, and eliminates the possibility
of a sound tech twirling knobs to balance the sound..
so you need to be more honest with players who are
too loud and tell them to stand back...we have used
a microphone like this for radio studio performances
as well as at a bluegrass/acoustic jam.
