Re: Micing death metal vocals..?
Shure SM7? People do rock them handheld in the studio on occasion. It's a bigass dynamic, and popular for loud vocalists. It's currently a very hip mic among metal recordists for vocal work. I haven't used it on vocals myself, though it's going into the mic shootout when we do vocal sessions for the Garda record.
EV RE20 is another option here maybe? Again, another LDD- large diaphragm dynamic. This, like the SM7, was a radio broadcast mic. You'd recognize these things if you saw 'em in this context, I'd think. This, I have used as a vocal mic. (On a live radio session, go figure. They had a bunch of them around.) Both of these will get you your lows; they wind up in kick drums and on bass cabs and the like. They have mids to them though, unlike modern specialized kick mics. Also, think "radio announcer voice".
There's handheld condensers, too, meant for stage use, but I can't speak for them and how they sound.
I've tried ribbon mics on vocals before, but I found them too dark.
Now, a good large diaphragm condenser will serve you well on... probably everything. It's about the least specialized sort of mic there is, and the handful of Internet Warriors who say it's an inappropriate choice for metal vocals have probably spent too much time huffing paint behind the dumpster because it's fine. You might want the color or pickup pattern of something else dependent on your source, but of everything it's probably the least likely to be the wrong option. Be wary on drums because it will bleed, and that bitchin' snare can turn into hi-hat Hell come mix time for example, but I digress.
