I am astounded at the number of profiles available that use the SM57. Including the commercially available profiles. I personally don't like the SM57, especially when pointed at the cap.
I guess many users only have a few Mics and that must be the most commonly available. so there is no confusion. Even some of the commercial profilers who use a Royer 121 have too much proximity effect.
It seems a shame that there is not a common standard for indicating mic distances and position.
