Yeah it's a Peavey PVM 520i.
It won't work for Art, however, as it's brighter than a Sennheiser 421. (more "bottom" than SM57 and "top" than MD421)
Although...
It's less bright than the current 421 MKII model!
The 520i is best suited for when you want to chop through a mix.
If you want to stick to the RE20 idea, the EV PL20 is the same microphone with a different paint job. They run about $75 or so
less used, than a used RE20. Be careful! If the element needs
replacement, it's over $200. A good practical alternative is the
EV RE15 and RE16 (has foam pop screen). Both fine warm vocal
and VO microphones as you may already know as a DJ.
In dynamics, another excellent microphone for basses is the
Beyer M88 (or M88TG). It has a massive proximity effect if you
start closing in on it. Haven't had the pleasure of trying
a SM7
yet, but that could be another winner for your voice type.
The M88TG allows me to "cheat" and sound like a REAL bass!
I also like the Studio Projects B1 when singing (high bass) as it
has a nice firm "bottom" (think J-Lo

), and relatively neutral
response. A lot of selection can be based on your engineering
skills (or lack thereof in my case). Many advanced pro engineers
like a condenser with a more hyped top end response like a C1
or V67, then they'll "de-ess" the signal during mixing etc., to fit
it better in the mix. I'd rather just simply lay down anything destined to be serious, and take it to a local pro studio to have it mixed and mastered properly.
The main reason I like the VTB-1 so much is that it's very quiet,
even when you run it at/near full gain for dynamic microphones.
It shines particulary with the Sennheisers and Beyer's which
are rated at 200 Ohms, and does very well with the EV RE16 too.
One advantage of some of the voice channels, like the Symetrix
520 (or 520e), is that could pick one up on the cheap used.
Then you could have Jim Williams at
www.audioupgrades.com
beef it up down the road to a higher sonic standard.
IMHO, the VTB-1 pre is superior to the "stock" 520 pre's BTW.
Less critical if you'll be using condensers, like the guys have said.
