Unleash Vintage Synth Magic with the Pigtronix Resotron Tracking Filter

Prophetic Synth Tone

The Pigtronix Resotron is your time machine to the prophetic synth tones of the 70s, now available for guitar, bass, and beyond. This analog filter pedal captures the essence of vintage keyboard synthesizers, featuring a 24db/octave state-variable filter based on the iconic SSM2040 chip found in legendary synthesizers like the Prophet 5 and Octave CAT. With Up and Down sweeping modes, along with a Sensitivity control that responds to your playing dynamics, the Resotron delivers the complete spectrum of classic envelope filter sounds. But it doesn't stop there; it incorporates an analog pitch-tracking system that dynamically shifts the filter's cutoff frequency in response to your notes. The Glide knob allows you to control the attack time and rate of filter motion, letting you shape the filter's movement to your musical preferences.

Knob-by-Knob Sound Sculpting

The Resotron offers precise control over your sound with a set of intuitive knobs:

  • Cutoff: Adjusts the filter's cutoff frequency when you're not playing.
  • Peak: Sets the Resonance "Q" of the filter.
  • Sensitivity: Dials in the dynamic response of the filter cutoff in ENV modes.
  • Glide: Determines the attack time for the filter cutoff in Pitch mode.
  • Blend: Controls the amount of optical compression blended in before the filter.
  • HPF / BPF / LPF: Selects the filter type.
  • ENV UP / PITCH / ENV DOWN: Chooses the filter motion.
  • Oscillate: Switches the filter into self-oscillation mode for pitch tracking synthesis in PITCH mode.

Drawing on Synth History

The Resotron's pitch-following effect is akin to the "key-follow" function found on classic analog keyboards. Using an all-analog pitch-tracking circuit to manipulate the cutoff frequency, this pedal introduces breathtaking filter motion to the world of guitar and bass, delivering a stunning array of creative possibilities.
