I guess the muddiness of the mids and the disappearance of vocals is caused by compression with the Bongiovi AGC (I hear these effects, too).
There was (is?) a profile creator but only commercially available to companies as far as I know.
Personally I sometimes applied small changes by hand to the profiles in the past. However previously profiles were just saved in a folder and now in a database, so it’s no longer possible. 🙁
