After having recorded a bunch and trying a bunch of different mics here at my home studio, I've finally found the recording mic setup that I think I'll keep for a while. The pleasant surprise is that it's really cheap as far as such things go. A friend at my university is into recording in a big way, and does a lot of professional recordings, including the Louisville Orchestra, all of the school ensembles, and a bunch of contract concert location work. He's a nerd about recording gear the way the TB folk are nerds about bass gear. He's been bugging me to try these new small diaphragm condensers he's been using for a while now. They're from a Swedish company called Line Audio. The SDC's he's been raving about are called the CM3 microphones, and in addition to being really cheap (about $100 each, once you convert from Euro to dollars), they are also incredibly small and light - about the size of an XLR connector. He kept telling me how he couldn't really hear any difference between these and a pair of Schoeps mics he used that cost about $1500 apiece; I'm not enough of an audiophile to comment on that, but he's not usually a person who is effusive with his praise. But the best thing is, for recording, a pair of these tiny little wonders in X/Y configuration sounds better than any other mic I've used here at home, and in my opinion also better than most of the large diaphragm mics I've used in the studio. They have a wonderful openness to them, and they spec as almost completely flat within the useful range of the bass. I wouldn't recommend trying them live onstage because the cardio pattern is wide, but for solo bass, they sound amazing to my ears. I ordered a pair of CM3 for the bass and a pair of OM1 (omni version) for the piano, and until then I'll be using the borrowed ones. Just thought I'd pass along this info in case anyone is looking for some nice and affordable recording mics.
