I'm thinking of buying a better vocal mic that the SM58 that I have now. The Beta 58A is at the top of my list, because that's what my old singer prefers, and it would be nice to have one in the locker for her when she comes in from the west coast for our occasional reunion shows. The rest of the time, it would be used for vocals in my home studio/office/family room. I'm sticking to dynamics mics since it's not a real "studio". It's not a bad room, but it's not treated at all. I think a LDC is just going to pick up a lot of the room's failings, so dynamic it is... but a better dynamic is probably worth the bucks. So, what is your experience with the Beta 58A and its mate the Beta 57A? How do they compare to their older brothers the SM58 and SM57 (with which I have years of experience)? How do the Betas compare to each other? And, should I want to use them for guitars (mostly electric, but also acoustic), how do they each behave in that application? Since this mic would be doing double duty on stage and (mostly) in the "studio" I'm not considering studio stalwarts like the SM7 and RE20.
