Similarity
citedBlended 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. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

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 Spaceman Artemis is a hand-wired boutique modulated filter built around a two-pole state-variable design with simultaneous high-pass, band-pass and low-pass outputs. Unlike most filter pedals it does not force a choice between responses: a mixer section blends them, so combining high-pass and low-pass produces notch filtering, and modulating that notch with the LFO yields convincing phaser and vibrato voices. With up to 10dB of boost and infinite cut per band it offers more tone-shaping range than many dedicated EQs. A seven-mode modulation bus drives the filter from conventional sweeps to outright bizarre animation, and envelope control sweeps the filter in either direction for vocal, quacking, funky auto-wah movement or downward synth-like swells. Built in Portland, Oregon with true-bypass relay switching and soft-touch footswitches.
