We have a number of concerts scheduled this year in our small auditorium. Most of the acts are "acoustic", so that means getting a number of Shure SM57 microphones or equivalent for the guitars, banjos, mandolins, etc. What about drums? Do I need microphones for the drums? The house (and stage) are small. Stage is 30' W x 23' D in back of the proscenium (which is 16' H x 30' W). The house is maybe 40-45' at the front and widens as it goes back to maybe 60' or so. The house is maybe 75' from the proscenium to the back. Should we consider microphones for the acts which have drums? If so, which types and how many?
