Like a time traveler from the tape music studios in San Francisco and New York in the 1960s, this dual filter (based on the core of a classic all discrete transistor filter built way back then), arrives to your studio.

The left side is a high-pass filter with two cutoff CV inputs, each with a reversing attenuator and voltage-controlled resonance. The right side is a low-pass filter with two cutoff CV inputs, each with a reversing attenuator and voltage-controlled resonance.
These old school filters will not self-oscillate, but they will screech and growl with the best of them. No IC amplifiers anywhere in the signal path.
