Come on, chessrock, I've seen a c3000B used very sucessfully for steel strung, Irish violin, in both live and studio settings. I have to go with the rock man and say *not* for heavy metal. I can't see this mic being the thing for a screamer. Just try the singer on a clean LD like C1 and a tube mic like Solid Tube, NTK,TB1,T3, etc., and a good dynamic (SM-7, say) He (she?) will sound good on on one of them, assuming they sound any good to begin with.
My best bet is the dynamic. At a current $300 or so, the dynamic is also cost effective, and it will be more like the stage mic the singer's probably used to. I don't own SM-7, but I have auditioned it and it's on "the list". Knock yourself out.-Richie
