I am no real vocalist. I just sing some background voices in our band or sometimes a single song. And my voice is rather weak and more on the low end.
My experience with the classic live mic (Sh... SM...) was that I did not hear me at all. It seems as if it only works if the singer is shouting loud in a quite high voice.
So I had to find an alternative and I tried several entry-level mics from Sennheiser, Shure, Beyerdynamics, AKG, Samson, ... I kept some of them. Some were sold again. Some worked fine.
But after reading some recommendations for the Rode M1 I gave it also a try. And what should I say? It's great!
It produces a nice clear sound that is easy to identify in a whole mix. I still have to tweak the EQ to reduce the bass because of the proximity effect. But other frequencies can be left flat.
I have no noticable problems with feedbacks even though my voice is not that loud.
For me this mic is a great value for the money.
