Go Sugarfreeboy! Yo Soundchaser! I'm glad you got the point. I don't record different people every day, but I do it a lot, including some pretty weird instruments- Viola diGama, Persian Zarb, Crumhorn, and even the dreaded accordion! My wife is a harper. I record a lot of chamber music, Middle Eastern dance music, and medieval ensembles, aside from rock, reggae, folk, jazz, blues, bluegrass, and a 12 part Science Fiction radio play with multiple live mics and stock tracks.
What I find interesting is that you like the C414, and are not a fan of the Bluebird. I find them to be rather similar sonically, and I stick the Bluebird in places where I would use the C414, but it's already being used (unfortunately, I only own one C414). I picked up the Bluebird recently at a pawn shop, and it's been seeing quite a bit of use.
The SM7 I use mostly for voiceovers, and oddly enough, although I don't use it for *my* vocals in the studio, as a rule, it is my main live vocal mic. It sounds great through a small PA, and is very feedback resistant. My main studio vocal mics (for me) are the B.L.U.E. Kiwi and Rode NTK. On my own voice, for a studio dynamic, I often use AKG D770. The key is EQ, or lack of it. I can make the SM7 sound good on my voice with the right amount of midrange boost, but the D770 sounds good with no EQ at all. For other voices, I use other mics.
It's weird- I work with 4 female vocalists, and every one of them hates the Kiwi (or it hates them, I'm not sure) Mo, the contralto, uses Rode NTK. Susan, the Alto, and Carolyn, the mezzo soprano, both use Oktava MK319 (which I bought at GC for $50). Wendy, another alto, uses the C414. For other material, Carolyn and Wendy both use AKG C2000B. That's exactly my point. Mics are like shoes. They either fit, or they don't. Cheap shoes that fit are better than expensive ones that don't. Instruments are the same, although not as variable as vocalists. If you've got a lot of different feet, you have to have a lot of different shoes.
Sometimes I get a mic without a clue what it will be good for, just because the price was right, and I find it on the "B room" equipment lists of major studios, so I figure it will be good for *something*. In so doing, I find some hidden gems that nobody really ever used much for that purpose, or aren't respected much at all. Needless to say, there is a wicked long list of great mics I don't own, and can't afford, so I have to make the most of the ones I do have. Here's the short list of the mics I use most often, and what I use them for. I have left out a bunch of mics I own but rarely use:
B.L.U.E. Kiwi- main vocal mic. My most expensive mic, I use it for almost nothing but my voice. It's the shoe that fits *me*.
AKG C414B-ULS- acoustic guitar, especially in a dense mix. Almost any acoustic instrument, and almost any percussion that isn't wicked small (chimes) or wicked big (kick). It's a standard on Djembe. Certain specific vocalists- one in particular that sounds like Celine Dion (who happens to often use a C414)
B.L.U.E. Bluebird- almost anything I would use the C414 on, but it is already in use.
AKG C2000B- Good on cheap acoustics, truly great on rack toms, but here's the weird thing I never expected- it's simply my best cab mic, hands down. Violin/viola,cello
AKG D770- snare, vocals, voiceovers. This is an underated gem I use anywhere that most folks would use an SM57.
Shure SM7b- voiceovers, live vocals, brass/sax (studio or live), floor toms. All-purpose live instrument mic.
AKG D112- kick, standup bass, some voiceovers, especially people with deep voices. It's perfect as the bottom mic on a Djembe. Bass cabs if the bass player insists on mic'ing a cab.
Oktava Mk319- female vocals, especially if I want to tame one that is a little shrill.
Rode NTK- vocals, especially ones that are loud enough to get the tube cooking- rocks on blues, R&B. Some acoustic guitars.
Neumann KM184- Jazz and country overheads, harp, piano, nylon string guitar, woodwinds, clarinet. Also very good on stereo ensemble recording-choirs/orchestra, etc.
Studio Projects C-4- Anywhere I would use the Neumanns, but I'm afraid they'll be broken or stolen. Excellent on acoustic guitar, especially nylon string.
Oktava MC012- Rock/Blues overheads, violin/viola/cello. Like the C2000B, the color helps to tame bow scratch.
B.L.U.E. Baby Bottle- Certain vocalists, both men and women, usually ones with voices that are bright and clean.
As I said, I have some other mics, but mostly, those are the ones I use 90% of the time.-Richie
