I've been playing around with it for a while trying to work out the best way to use it. Do you only reference the eq curve recommended or can't you just run it as an eq replacement and then bring the volume after it?
The Linear EQ 64 is good for precision equalisation edits so that may be the candidate for the job on the Master Bus. Running some older renders which I know were bad, it almost magically fixed the mixing errors however I'm not 100% how I would use it.
Also I must mention how running the Dr. Dre Beats profile made everything sound terrible. I should have tried some hip-hop.
