For me EQ is about solving problems rather than shaping tone. A bit of bass cut to solve bassy howling and booming. A mid boost (or two, sometimes) to cut through. It's never more than that. And the more knobs you have, the more opportunity to screw everything up royally. If there are no problems, don't fix what ain't broken.
Well, actually, I do add a bit of honk, now and then, so I guess that is tone shaping....:D
And when it comes to roll off tone controls, I have only ever used them on P basses. But they really do work on P basses!
