Basically, what Chessrock said. That aside, they're $424 at the Sound Room, and worth every penny of it. But $424 is not $300. While I haven't used them, numerous people here whose opinions I respect have suggested MXL 603's. Somebody who actually uses them will give you the lowdown. One thing I might try is one Oktava MC012. While they aren't matched as pairs, and quality control is flaky at best, one of them can be had for $150 or less at Guitar Center. This is the best cheap mic I've personally heard on acoustic guitar.-Richie
