Micing ride cymbal with sm57?

[sloom]

For hi-hat, sure. You're probably not talking about the same subtlety as with a nice ride cymbal, or crash, etc., where you're getting a lot of overtones. It tends to be more of a defined, attack-oriented sound, and often of shorter duration than other cymbals.

Tic-tic-tic..., or swash/swash/swash...; and maybe it opens and shuts- a very defined, consistent kind of thing. In rock music, it's kind of an accessory to the snare drum.
