-Built like a tank, seriously.
-Great for grunts and deep voices.
-Not recommended on natural airy voices.
This mic has swiftly become my goto workhorse and I absolutely love it! I use it mainly on vocalists, overheads and acoustic instruments, but you could use it on almost anything.
This mic is very sensitive so you'll find yourself using the -20 dB pad a lot. Proper mic placement and room treatment are important.
The figure 8 pattern as well as the omni-directional are excellent and very useful for duets and choirs. The frequency response when switched to cardioid changes just a tiny bit and opens up an airy brightness which is great or bad for vocals, depending on the source.
In my experience, AT2050 shines on deeper vocal styles, metal grunts and rap voices. When proper mic distance is observed by the vocalist, death metal growls will sound bright and not at all muddy. The downside is that harsh high screams have their harshness amplified unless the vocalist repositions. Also 'breathy, angelic' style female vocals can sound harsh, albeit full.
Observe correct mic positioning. Observe adequate room acoustics. Discard muddy SM7b. Enjoy bright AT2050!
