Experience the Pigtronix Resotron, a versatile multi-mode filter effects pedal designed for guitar, bass, and beyond. Inspired by ’70s era synthesizers, Resotron brings authentic analog sounds to your music. Featuring a 24dB/octave filter based on the legendary SSM2040 chip, this pedal offers Low Pass, Band Pass, and High Pass filter options, allowing you to sculpt your tone with precision. The velocity-controlled UP and DOWN envelope modes respond to your playing dynamics, while the pitch-following envelope function with variable GLIDE control lets you create expressive, synth-like sounds.
The Resotron’s OSCILLATE function transforms it into an analog synthesizer pedal, allowing you to craft unique tones with the CUTOFF knob and voltage-controlled amplifier. The on-board Philosopher’s Tone compression stage adds punch and volume to your sound, which can be blended in using the BLEND control. With active CV and passive TRS expression pedal inputs, you can control filter sweeps and modulation with your feet. The TRIGGER input enables external audio sources to modulate the filter, opening up new possibilities for sound design.
Key features include adjustable PEAK and SENSITIVITY controls, allowing you to tailor the filter’s resonance and response to your playing style. The GLIDE control sets the filter’s movement between notes in pitch-following mode. With its rich feature set and analog sound, the Pigtronix Resotron is perfect for musicians seeking to expand their tonal palette.
