Why pay more?
The SM58 is famous for its use in live stage work, and for good reason: good sound, legendary durability, and good off-axis rejection. But I'd like to tell a story about the SM58 in a recording setting. I have a Neumann TLM-193 and a Blue Spark, and I'm always striving to get the best sound out of them, you know... "that" sound. The other day, I listened to a song by a fellow home studio recordist, a very talented 19-year-old. The whole production was outstanding, and it was the first time this guy had included vocals in a song. "Your vox sound fantastic," I said to him. "What mic are you using?" "An old SM58." "The piano sounds great, too, is that a vst or a real piano?" "Real. I mic'ed it with the same SM58." "And the violin?" "Same SM58."
So, he was getting at least the same (if not better) results from an SM-58 run through an el cheapo ART tube pre-amp as I was running my precious Neumann through a much more expensive front end. Of course, skill has a lot to do with sound quality -- but this kid has no real technical recording knowledge. He just pointed the mic at the source and moved it around until it sounded good. And in any case, if it really is all about skill, why spend more than the cost of an SM58, especially if it's this versatile?
