I use Studio One. Just like they suggest, FrontDaw is the first plugin insert.  Just dial in the amount of saturation you want with the input, then Hi-Pass to taste, then cycle through the flavors of saturation. I find British darker, US more clean and open, and German more gritty. Then play with the Mojo until you like it. It doesn't work for every track, but darn near. Really a great plugin! *
