The Beta 58A is a premium vocal mic ideally suited for professional lead and backup vocals, either on stage or in the studio.




Both are designed for vocal use and have a bright midrange and bass roll-off. The Beta 58A has increased sensitivity and high-end frequency response which results in a cleaner more detailed sound. It also features a supercardioid polar pattern compared to the SM58’s cardioid, giving it greater unwanted sound rejection and more resistance to feedback.

Product Rating

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
