My wife is an alto/soprano that sings metal. She also does some nice growls. I own an AKG C414, but it can come out a bit "Harsh" on the high end (I use an Avalon preamp). What works for us is a Behringer B1. Sounds amazing and at sub 100 dollars is an amazing deal.
Took me 20 years to build out my studio. Learned valuable lessons along the way. Every time I paid someone to do my recordings I was disappointed with the results.
Spent 20k on the room and equipment combined over the years but the results are stellar. You don't need big bucks, just care and time.
