There are many great lead vocal microphones. The SM 58 microphones by Shure are the most popular due to the durability and consistent great quality sound. Many Manufacturers such as Peavey, Audio Technica, and Bauer Dynamics all produce outstanding quality mics. Unlike guitars, it is difficult to find a music store wher you can try out vocal mics.
What ever mic you buy, at practice, to avoid feedback and to hear yourself once and for all at any practice, on the road, attach the Vocal Acoustic Monitor to the mic. You will be able to hear yourself without turning up the P.A. to the point your mic still feeds back. The VAM will allow you to hear yourself so you don't have to strain your voice.

Simple product, highly effective. Forget about Live use when you see the product, open your mind to it for practice. Have VAM with you in a gig bag when you play a venue where there are poor or ineffective monitors.
You can use VAM as a hand held to train your voice on the go, without a mic attachment. You will never cup your ear again.
