Don't put them near the cymbal edges, though! As the cymbals rock you'll get weird phasey or swishy sounds.
They don't go close to the cymbal's edge. That would defeat the object of not getting lots of cymbal sound.
Mind you, sometimes, those phasey and swishy sounds are pretty neat.Sometimes in the past, I've caught this deep resonant aftershock that hums and whirrs, menacingly. Great atmospheric sound, on the right song.
Grimtraveler: I'm interested in your approach to overheads. By under the cymbals do you mean like a room mic in close proximity. What is your placement like in that position? XY, Spaced Pair.
Whenever I've tried a room mic thingy, I've usually used that mic as a kind of super overhead, up high, pointing to the centre of the kit. I did once use a room mic placed in the back of a van {I was recording in the warehouse at work} and it picked up the entire kit {with a surprizingly good kick} better than any overheads I've ever managed !
The reason I place my overheads as I do is because the drummer that I play with the most, being young would sometimes get a bit wild and on occasion, was hitting the cymbals so hard that it overloaded the mics and I learned firsthand about the dreaded digital clipping. I also found that the cymbals used to be the dominant sound in the O/Hs, even though the mic wasn't close to them. But by putting the mics below the cymbals' height, they pick up the body of the drums and seem to level out the cymbals. They're never dominant anymore, no matter how wild the drummer gets {he has calmed somewhat !} but nicely balanced.
I don't use XY or spaced pair because I look for the drums to be centrered as opposed to dead centre. I'll usually pan the snare slightly to the right and the kick slightly to the left. So the overhead {well, underheads really} mics could be placed in a variety of ways. I might do one adjacent to the floor tom and the other slightly off the hi hat but under it's height. Or both might be in front of the drums, one to the right of the kit,
the other to the left. I think I use variations of the Glyn Johns method without the precise measurements and with close miked toms fed in with the O/Hs. It sounds a little higgledy piggledy but it works for me. I've been very experimental with recording drums since I had more tracks to devote to them {I used to have a single track for drums} and I daresay, I'll get around to XY and spaced pairs and other ways at some point.
