There's not much that can be said about the Shure SM-58 that hasn't been said already. For nearly 50 years it has been the microphone of choice for the world's top bands, and a fixture on stages large and small. I honestly can't remember the last time I was at an open mic or playing in a church that didn't have at least a couple of these mics at the ready. The ubiquity of the SM-58 is not hard to understand: It's responsive and dynamic, and rugged enough to handle the rigors of regular stage use. Plus, after all these years, it's still only $99. You'd be hard-pressed to find a better mic for under a hundred bucks, and I recommend this without reservation
While not the fanciest dynamic microphone in my arsenal, I consider this sturdy workhorse indispensable. There's a reason it's the standard!
