Hello all - This guy I work with asked me to ask this question here - He'd like to make demo recordings of his group, which rehearses at his house and he's trying to avoid unnecessary studio fees. At present, he just uses an ordinary el cheapo vocal mic plugged into a good quality tape deck, set up so that it's pointing at the instruments in his living room. He's wondering if using a high end mic like an SM57 would significantly improve the sound. He only has budget enough for a single mic. If he needs to, he's got software on his computer that allows him to record track by track, and the mic could be used for that too. So the question is, given that it's just a makeshift setup in his living room, which hasn't been turned into a studio with muffling and all, would an SM57 produce better recordings (it's all for demo purposes, no more), enough to justify the investment? Thanks!
