So I practiced with drummer the other day in my place, the room is decent size, 14' by 25' maybe? I have an SM-58 mic and an acoustic guitar hooked to a 180w berringer amp which is technically a keyboard amp, but when the drums started going we couldn't hear the guitar or even the vocals sometimes, should the drummer play softer or should I invest in a better amp? Any other tips on things I should buy or change the room set up? Not rich on the budget but not struggling either. Drums were against the wall.
Going to try to post the rehearsal area pic:
