This question is for the more experienced mastering engineers: With regard to boosting/cutting EQ while mastering a tune, do have a general rule you go by as to how much is accpetable versus labeling the tune as "in need of remix"? Obviously, if you need to boost or cut a freq. by 6db there is a problem. But do you try to stick within a certain range, say +/- 1 or 2db or what? Thanks for any help.
