Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Maestro Agena is an all-analog envelope filter, part of Gibson's revived Maestro pedal line, delivering classic auto-wah and funk filter tones with simple, expressive controls. A three-knob layout of Sense, Attack, and Decay shapes how the filter responds to pick dynamics, while a two-position Mode toggle selects between Hi and Lo frequency ranges. Hi mode emphasizes higher frequencies for a crystal-clear attack that punches through a mix, and Lo mode focuses the filter lower for a rounder, deeper quack. It changes the timbre musically without sounding overly affected, and true bypass preserves the dry tone when off. It suits funk, fusion, and players wanting an easy, vintage-flavored envelope filter that does its one job extremely well.
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.
