I've been extensively modding the EQ in my Wheatstone console and trying to get that type of shelf from a state variable circuit. I got a shelf with adjustable resonance, where it has a peak at the top of the slope and a dip at the bottom of the slope. Still working on a shelf with only the dip. It may involve combining the BP and HP outputs. I know it can be done, because the Undertone Audio console does it with a potentiometer that fades between bell and shelf.
