So Why is The Shure 58A Beta Better Than the SM58?

You’ll hear the difference right away in the slightly higher top end response of 16kHz which is 1000Hz higher than the 15Hkz rating for the SM58′s. This isn’t a huge difference but for live stage applications it could be enough to avoid tweaking the EQ rack and possibly avoid some feedback issues… engineers have a better time with this mic than the SM58.

Secondly, Shure have improved the shock mount on the Beta 58 giving it better isolation throughout the it’s entire body… if you rub or slide you hand down the mic you’ll notice less noise. As tough as the SM58 is, they’ve made the round cover grill even tougher on the Beta.
