My hack vibe on it is....
That if the mic roll-off is not TOO drastic - by that I mean - that I am confident that it is letting through all the bass I am EVER GOING TO NEED on that signal.. then it's a good idea to use it to 'clean up' the signal. (like to eliminate sub bass from foot taps during a tambourine take)
Or on vocals - I may want the singer in on the mic to get the voice warmed up a bit by the proximity effect - but flip on the roll-off to reduce some of sub bass I don't feel I need.. (seems like a contradiction in terms I know but.....)
Like any filter or cut - it can be fun to follow it with a boost..
Cut say 60hz but then crank 100hz..
It all depends for me...
I tend to find the mic pre roll off - to be a secondary thing to reach for. So I try mic roll of first - then, if that is not working, move on to useing the mic pre roll off.
I like the roll off on my hardware Focusrite 215 & my Sony Oxford plug ins
Try it every way and exercise your ears to see which works out best!
