In the end, it is how, what, and where you use any given mic. The mic is a choice in any given environment based on what is being mic'd, the room it is being used in, and the gear that it is being run through. It's how you use it and how you are driving it.
And yes, as someone mentioned in an earlier post, SM58’s has seen use for vocals in million dollar studios, but then again; so has U47’s.
I can fix anything with a Phillips screwdriver, a small hammer and a wood saw, but even though it might not look any better, it sure as hell would be so much F*CKIN’ easier, let alone faster, if I had the right tools for whatever I’m about to fix.
I have ALL the audio tools I could ever dream off in my homestudio - and it makes the recording, mixing and mastering process SO much easier - and so much more fun. That allows me to focus on the content instead.
