A MS-20 style LP/HP/BP resonant filter with simultaneous full control amplitude envelope follower (sweeps up or down), stomp enabled LFO through audio range modulation, and 'Ghost Wah' momentary stomp/swell. Pre filter gain is available, and Filter cutoff can be centered anywhere from below to above audio range. LP mode is -12dB per octave. The filter can be pushed into self-oscillation, and can be used as a stand alone analog synthesizer. This thing is ANY filter freaks wet dream. Suitable for Guitar/Bass/Line.
