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 hipass filter with two cutoff CV inputs, each with a reversing attenuator and voltage controlled resonance. The right side is a lowpass 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.
