Last year I was touring (FOH) with an amazing band.
https://youtu.be/LUB5552HkT4
The drummer has the loudest kick and snare I ever heard; the keyboardist plays bass lines with an electric piano into a 2x18 bass cabinet and two wedges; two heavy distorted guitars blasting on the stage; and the vocalist (who also plays acoustic guitar thru an amp) sings so weakly despite the explosive band behind him.
Oh, and the vocal sound need to be always distorted (I used a Jhs Clour Box at FOH position).
This hell has been tamed thanks to Audix Om7.
This is an amazing mic.
You just turn up the fader and it simply sounds good.
It has just the right focus.
It is a directional mic but he surprisingly have less proximity effect than wider mics.
It has an extremely good rejection to feedback so you can turn it very loud in the monitor speakers (you need two speakers or one off axis speaker to take full advantage of its hypercardioid pattern).
It is very directive so you have to get used to sing directly into it but as soon as you hear all the benefits you will learn quick.
I used this very mic in the studio too, recording guide vocals live in the room with the band.
It sounds like I'm involved with Audix but I'm not.
This mic just saved my life a lot of times!
Another very good rock vocal mic is Shure Beta 57, in my opinion.
Hope It helps...
