The Beta 58A is an amazing dynamic microphone that might alleviate some of the stress associated with its more cost efficient cousin. That is, the Beta 58A, in the confined live scenarios in which I have utilized it, has demonstrated a much broader sweet spot and completely eliminated some severe feedback issues. For vocalists that like to pull back from the mic a touch to really belt those sustained high (or, really, any) notes the Beta is a dream. This same effect helps if one is experiencing sibilance or "popping" complications and needs to sing past the microphone as opposed to directly into it.
