yeah, same here...,
there are a lot of ppl who think, that its not good, but i realy like it and do it.
i place mostly the psp vintage warmer or ozone in the master. depends on the material and what i want it to sound like. for metal stuff, i take ozone with the multiband and a liuttle bit loudness maximiser just to bring it to 0db (but without hiting). if i am doing more rock stuff i take the PSP plug mostly.
but i first start mixing without. til the song starts to get rolling. busses compressors and eq`s where they realy are needed. when the song rocks, and i have to do the details, i already know where the song has to go to. than i place that stuff in the master chan.....
another good point is, that i mix 1 song like that, till he sounds good, than i import the session data to the next song. with the master stuff of course. so all the next songs will sound realy common if its needed.
just pay attention, that you dont use the things in the master chan to much as mastering effects. like making realy loud and bright and so on....its just for the feeling....
and dont be shy. if the sound is good in the end, than no1 will blame u for having something in the master chan
