Which Vocal Mic?!?

Do I still need this if I have Rode NT1a, AT 4040 and SM7?

(Serious question!)

nope, it outperforms the nt-1 IMO but with the 4040 you've got a decent LDC and the sm7 is killer anyway.
I just recommended the HM-1 cause I think it's the best bang for the buck but I don't think it's "better" then 4040 or sm7 (different perhaps, yes) the 4040 and sm7 are more expensive though.

I'm considering a couple of HM-1 myself for bright girl voices cause my usual goto LDC is the 414 xlII wich can get fairly bright on some voives (though I love it one alot of things).
