Usually in a live band situation, it sounds better if you pull 200 to 250 Hz down a bit. It might be stage bounce that causes the abundance of acoustic energy in that frequency range, but it's usually there and if you compensate for it your mix will sound cleaner.

I'd venture that at least 80% of my shows end up with at least a slight cut somewhere in this range. That number gets close to 100% in an indoor or shed environment.
