SM 57 is not a vocal mike...
...is a big-time misconception. It is one of the best all-around workhorse vocal mikes made, especially for the price. Shure list vocals as one of it's primary uses in their own instructions. I do live sound, and I highly prefer them to 58's, as they reduce feedback and help keep the mix clean. But 58's are good because most singers don't know how to sing within the ideal pickup pattern of the 57, or at least don't know how to stay there throughout a set. You can just kind of sing anywhere within a reasonable range/angle to the 58 and you will get a decent-sounding signal. Move off from a 57 or sing into it at a funky angle and the tone gets bad and the volume gets quiet. Additionally, you can easily fine tune the EQ of a 57 by changing your distance from it. Not so much with a 58.
If simple and cheap is the name of the game, get the BLUE SNOWBALL
It's a large diaphragm (full bass response) condenser (fast transient response, warm, full tone) microphone that is its own interface, and connects to your computer directly via USB.
I recorded these 2 songs using only the BLUE SNOWBALL and Reaper. I'm not a great mixer, and my buddy Kyle is not the best singer, but this gives you an idea of what you can do in your basement with nothing but a $99 microphone.
