Well I`m not going to go into a long tirade about how rigs work, and how close to the limit most are run etc.
However, if a rig has limiting, it generally sounds shit.
Pumping the mids, also sounds shit, good at home, shit on a rig.
Either you trip the limiter, and get a crap signal through the speakers, or you risk frying the mids or tops.
Some tunes have it. But these tunes are compressed and mastered, so it really doesn`t effect the rig as much as some clueless goit pumping the eq with a stupid "look at me" grin on his face.
Subtle tweaks beyond the half way are ok, but sudden pumps in the EQ are stupid, and the domain of amateurs.

I implore people not to do this.
