PigtronixResotron Tracking Analog Filter

Pigtronix Resotron

Pigtronix's Resotron is a fully analog filter based on the SSM2040 chip, that was a crucial element for the unique sound of the legendary Prophet-5 synthesizer. The pedal is comprised of a 24dB/octave state variable filter with the ability to self-oscillate, ramp up/down modulation envelopes, and a pitch-tracking system that moves the cutoff frequency around based on the incoming notes. Additionally, ‘glide’ parameter is implemented to set the slide time from one note to another for a smoother response. Altogether, Resotron is an excellent pedal choice for bringing back that ‘70s sound to the modern sonic palette.
