On a somewhat unrelated note, two of the guys that run PT Expert said this would be their choice as their desert island "harmonics" plug-in. I found that interesting. I know saturation/distortion adds harmonics, but I've not seen the Sat. Knob referred to that way.
Saturation, whether created in an SSL pre's transformers, a Mesa Boogie head or a cheap fuzz pedal, is always a combination of harmonics and compression.
Softube's Saturation Knob is very good. I'm generally reluctant to use much digitally created saturation/distortion because I often feel it lacks something I can't define but can "feel" when compared to transformers, valves, diode clipping, transistor fuzzes etc., but the Sat Knob is something I use and find musical. If I could only have one saturation plugin that would be it.
D16's Devastator 2 is also pretty good, and Waves' Saphira are also pretty good in my opinion, perhaps because they're subtle as such things go, don't try and overdo things and blend nicely rather than sounding like a "glued on" addition to the original audio. At least, that's how they strike me.
