I'm an amateur sound tech. We've been using SM58 in our church for years now and our singers/song leaders liked it very much than the other mics that we've had before. Our singers are growing and we needed addtional mic so we thought of this Beta58A because of the good reviews. When I received it I cannot wait to test it myself and whoaaah.. For me, it sounded better than SM58. My songleaders have tested it and guess what... they don't want to use the SM58 anymore :)
