Over the past few months or so, in endevours requiring a microphone, I've been mostly hobbling along with whatever awful recording equipment I have lying around. We're talking defaults here. The background noise and quality drops I've been noticing recently have driven me to pursue a new, professional microphone. I'd mostly be recording guitar and vocals with it, maybe some woodwinds as well. Price doesn't really make a difference, but if I could save money that'd be great. I was considering a Shure SM-57 or 58, are those any good? Also, would I need an audio interface for any of these?
I'm a complete newbie at the subject; can you guys help me out?
