Good comments all!!!

What I am concerned about is when I DO have live players in that the room will become too live and there will be a lot of sound bouncing where things I don't want in a mic will find there way, there will be room reverb that I prefer to not have (that's why we have digital reverb units, right? to add it like we want it?). One room will be isolated for the drummer and I want THAT room totally flat.

The room is carpeted but the walls are bare, all drywall.
