Pigtronix Resotron Analog Tracking Filter
Pigtronix · pedal
The Pigtronix Resotron is an all-analog tracking multimode filter that brings vintage 1970s synthesizer character to envelope-filter territory for guitar, bass, and keyboard. Its 24dB-per-octave filter is based on the SSM2040 chip found in some classic synths, offering traditional up and down envelope-filter modes plus a unique pitch-following mode where the filter adjusts to the actual notes played rather than just pick attack, like an old-school analog synth. It covers subtle auto-wah variations for funk riffing, reggae rhythms, and Jerry Garcia-style leads, and can also coax phaser- and flanger-like tones. Onboard compression keeps things punchy without affecting sensitivity, and an expression jack allows foot control of the cutoff for conventional wah use. It also turns overdrive and distortion into creamy, near-fuzz tones.

Trade-offs
“Limitations include a specialized, synth-oriented voice and depth that take time to master, making it more of an expressive tone-shaping tool than a simple envelope filter”
