I went from a Shure SM57 to a Rode NT1, and nearly fell off the chair first time I listened. All that detail! Yes!
I know 57s are industry standards for guitar cabs and snare and such, so I know they're good, but for things like miking acoustic guitar, I've been trashing them ever since that day. Ditto 58 for vocals. I know, I know, others get good results... However, I've switched from the NT1 on my acoustic to the AKG C1000 because the small diaphragm mic picks up less bottom end I think, or at least sounds less boomy.
Now I'm looking for a great small-diaphragm mic for the same purpose. LI Slim suggested the AT 4047, and so far, that seems a really good option. They're flogging them at 8th Street for $499 with a set of cans tossed in. Can this be real? What's quality control like on Audio Technica mics? Occasionally dodgy Chinese capsules? Why so cheap at 8th Street? Am I being unnaturally suspicious? Uh... sorry about the slight digression from the thread... we're still talking diaphragms and mics for acoustic guitars, though...
