Jeez guys!!
Do we have to get back to basics here?!
You should
never need anything more than the correct mics, the right room, the right placement, and the right tuning. If you need to gate something or use foam or isolate or whatever, then you're doing something
wrong!
Either the drums are set up badly, or you're trying to dampen or muffle things and altering the natural balance of the instrument. And by instrument, I mean the WHOLE kit, not just one drum!
A. Tune the kit right. Don't rely on serious muffling and/or ring control. Nobody in the pro world does that. Good heads, drums and cymbals are all you need and you don't need to worry about anything else.
B. Acoustic treatments. Make sure your room is good. Some reflections, but not too many. Not too dead either!
C. Start with the basics. Set up a kick mic and a couple of overheads. See how it sounds, THEN add the other mics one at a time and see how it sounds. You can correct a lot of problems by doing things in the right order.
D. Pick the right mic and preamp for the right job. learn about cardioid and omni patterns and where to use what.
C. Don't use too much EQ. I can get a great drum sound without ever touching an EQ knob. If I do everything right, I will hardly ever need to EQ anything, if at all.
That's all I've got to say right now without more scotch!
