Depends entirely on the show, how it's supposed to sound and how much time I have.
No time -> compressor and de-esser on the DIA bus.
Enough time, I have a comp in every track, along with a de-esser.
Most often, cleanup EQs(notch and all) are first, then denoisers if I have them, then depending on material it'll be pre- or post-comp shaping.
My favorite EQs are EQuality and Renaissance EQ(6-band) for shaping, and EQuick for notching.
The De-Essers depend on how well they handle themselves. Pre-comp it's often the Renaissance DeEsser. I have not had the pleasure of trying out Massey's plugins. I'm real happy he's porting his stuff to VST now. I use plugins in more than just Protools.
The hot new thing in DeEssers is Fabfilter's Pro-DS. Just an awesome unit, which I intend to purchase as soon as possible, because it can gracefully handle almost everything.
