Used Pigtronix Resotron Analog Tracking Filter in Like-New Condition with Original Box


Resotron is an analog filter pedal that brings the sound of 70s keyboard synthesizers to the world of envelope pedals for guitar, bass and beyond. The filter at the heart of the Resotron is based on the SSM2040 chip found in the legendary Prophet 5 and Octave CAT synthesizers. This 24db/octave, state-variable filter provides the full gamut of familiar envelope filter sounds with Up and Down sweeping modes, as well as a Sensitivity control to dial in the response of the effect based on how hard you play. In addition to these vintage-correct filter tones, the Resotron incorporates an analog pitch-tracking system to move the cutoff frequency of the filter up and down. The pitch-following filter effect found in the Resotron moves around based on the notes you play instead of how hard you play. The attack time and rate of filter motion can be adjusted using the Glide knob to dial in how long it takes for the cutoff to travel between pitches.


  • Cutoff: Sets the cutoff frequency of the filter when you are not playing.
  • Peak: Sets the amount of Resonance “”Q”” of the filter
  • Sensitivity: Sets the dynamic response of the filter cutoff in ENV modes
  • Glide: Sets the attack time for the filter cutoff in Pitch mode
  • Blend: Sets the amount of optical compression that is blended in before the filter
  • HPF / BPF / LPF: Selects the filter type.
  • ENV UP / PITCH / ENV DOWN: Selects the filter motion.
  • Oscillate: Switches the filter into self oscillation for a pitch tracking synth in PITCH mode.
