I recently bought the last one at GC for vocals. I found when I got it home and tried it that it is respectable but on the dark side. If you've got some bright mics then it would be a good opposite flavor to them. It has a good detailed sound, no harshness or boominess. Just a tad on the darker side for my taste. I'll probably sell it and move on. If your recording a person with a high pitch voice it might counter that well? It's very well made.
I don't think vocals is really where the 44 shines.
My experience has been pretty much what Bob mentions. It's a fairly dark mic .. pretty scary how ribbon-like it is, in fact. Might go so far as to say that if you can't afford a decent ribbon, then the 44 might be a viable substitute. It's really smooth and easy on the ears ... handles transiets really well without sounding harsh.
I think Bob should give it more of a chance than he has. You will run in to situations where you need a mic that does what it does.
Vocals are the one thing this mic is not so great on. It is a great mic for dynamic sources like drums, ac guitars and elec cabs. It has a really focused sound that sits in the mix quite well. Vocals sound like a dynamic mic though. It does not bring open well defined vocals like a LDC would. It would be alright if it was your only mic since it shines at a number of things. If you had to use it for vocals, the sound would be very much like an SM57 except not as muddy.
