Thanks for the suggestions guys, but hold on a sec, my understanding is:
Parametric EQ = Curve, usually with points on it
Graphic EQ = looks like a bar graph

I find that the parametric is good for subtle changes, and graphic for extreme chops - the curve approach restricts you to "sensible" eqing, I find, whereas the bar graph lets you go screwy with it, so to speak. What I'm trying to emulate is Reason's vocoder in EQ mode, with some weird graphic EQ jumps, moving the shift pot around. You can get some insane filtering effects out of that.
