Until now I've been using a Shure Beta 58 with my Tyros. I've tried other brands and more expensive mics, but never found something that gave me better results (for my voice, of course) and it's as practical as a dynamic for live use. Well, I recently purchased an inexpensive Audio Technica condenser model, that is proving to be an even better choice. It has a hotter signal, lesser problems with feedback, better hi-end frequency response and it doesn't need phantom power (uses a small common 1.5 Volt battery). Another advantage is that it seems to provide cleaner vocal harmonies (when using the Tyros vocal harmonizer). I'm not certain it's as solidly built as the Shure, but I'm surprised that it's so cheap! Not sure, but it is possible that this is the same mic Tony W is using. The reference: Audio Technica MB 4K.
