I haven't seen one, but given the hints in this thread, it should be 
trivial for you to do that. In fact, it would be fairly trivial to make 
the property switchable or even a separate pot to control how much 
pass-band suppression you should experience, as you would simply control 
how much of the input will be driven to the diff-amp inserted prior to 
the resonance pot. Full (1:1) amount gives no suppression, while no 
amount gives full suppression.

It should not involve more than an op-amp, a handful of resistors and a 
pot to pull this off.

Cheers,
Magnus
