I've used these mics with great results. When I shipped my main set of mics away to get modded, I used the C02's for a few shows. They are pretty clean mics that are not very noisy. I've also used them onstage for drum overheads, they have an almost abnormal high gain stage before feedbacking. Great value, at about $100 per pair you can't really go wrong.
Check out this show on the archive:

Hope this helps.
Oh, one more thing, where are you located in NC?
