Currently I am bidding on another Shure wireless on
ebay. My other one is the UT4 receiver and SM58. I absolutely love it. With the receiver gain it;s like having a powered 58. With the gain all the way up you get feedback anywhere in the room.
Also like a condenser mic it picks up room reverbs at high gain.
The owner gets a kick out of leaving the room and singing in the bar area.
