I just wrote what I thought was an eloquent response to your question. Obviously I am not as savvy as I thought as it was lost with one keystroke. Anyway, the only way to find a mic that works for a particular singer/instrument, is to try one. There is no 'perfect mic for everything'. A 58 might work for voice 'A' and be the worst choice ever for v 'B'. That being said, there are many cheap mics available. Keep in mind tho, there is a reason pro recordings are not made with crappy, budget priced gear. A 58 may be the mic used, but it was probably routed through a $2000+ preamp and recorded in a well treated room with a highly experienced engineer who knows through experience which combination to try first. There are no easy answers. Just opinions. Mine are probably silly. LOL!
