When I say slammed, I literally mean there is almost no dynamics to the vocals. I mean this genre is slammed to death and back across the board, the only way to get the vocals up front and clear is to smash the hell out of them. Honestly I pretty much end up with limiter settings the way I use compression on screamers. Ratios in the 20-30:1 area, 10-15ms attack, semi slow release and set that threshold for some good GR.
I do want to try riding the fader around at some point and see if I like that, or vocal rider from waves (will probably snag that the next time it goes on sale). For now the above method is what I go with.
I try not to eq to much on vocals personally, YMMV but I tend to not mess with them much beyond some roll off on the top and bottom of the spectrum in areas that are not missed.
Then I send that to an aux (or group or whatever your daw's terminoligy uses) with both a multi tap delay set to usually quarters and half note taps on both the L and R sides of the spectrum and maybe a whole note or something up the center, set the feedback of those delays so they don't ring out to long. I actually don't like the amount that was used on that sample I posed of Randy's voice.
Then throw on some slight verb after that and I'm good.
That's whay I do, I've done other stuff but that works for me most of the time.
