The Shure SM-57 was originally designed by the Shure Brothers as a Vocal Mic. (first named the "Unidyne") It exhibits the "vocal peak" in its frequency curve, by design.
I still use one for vocals, they are great vocal mics for baritones.
An SM-57 with the Shure designed long foam boot can work and sound very much like an SM-58, too.
They use the same capsule.
Whenever this one comes upm I refer folks to this webpage, in which an SM-57was used for every track on the song featured there:
The "All '57 Song" I think (I KNOW) that a '57 is more versatile for home recording than a '58, although either can serve you very well. The '57, however, can be pressed into service as a vocal mic, guitar mic, wind instrument mic, stringed instrument mic, drum mic, etc. without much coloration. That makes it still a first choice for many on-location recording and broadcast soundstages. AND studio.
