I've been recording a lot more drums lately, and want to know your thoughts on overheads vs. underheads, as in mics underneath the cymbals. I usually use one condenser over the entire kit for cymbals and toms, and another dynamic mic under the second crash, ride, and (in my case) china. I find that I get a really great cymbal sound out of this underhead. I'm using an extremely cheap Samson R21 with a lot of midrange. I'm working with a very limited mic locker. Can anyone offer their experiences and preferences? Do you use all over, all under, or some mixture?
