Not having a lot of experience with microphones beyond those included in other equipment (such as those built into handheld recording devices), I was struggling to choose a good vocal mic. Based on recommendations from a singing friend (she's a singer - she didn't sing the advice) I started looking at the Shure range, and the SM58 in particular.
I didn't want to have to worry about phantom power, so the SM58 was a good choice, being a dynamic mic, and its cardioid directional pattern means it is less sensitive to background noise and feedback. Lots of singers choose these mics so who was I to argue. There are two versions - one has a switch to disable the mic - this is the one I went for.
When it arrived, it took less than a minute to hook it up to my amp and get it working - it sounds great and I'm very pleased with the purchase. Price was good, too!
What can I say about this? It's an SM58. So you know straight away that it is going to be as good as it can be. After messing around with cheaper mics in the past I decided to splash out and get one of these once and for all. It performs exactly as I knew it would and will continue to for years to come.
