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. Shown only within a gear class, and only where there's enough evidence to be meaningful.31% — somewhat different

The Chaos Custom Shop Sub Sonic Filter is a specialized low-cut filtering pedal for bass, designed to remove ultra-low, inaudible sub-frequencies that can waste amplifier headroom, cause speaker excursion issues, or muddy a mix without adding any audible tonal benefit. Built by Chaos Custom Shop, a boutique maker specializing in precise bass signal-shaping tools, it offers a more targeted solution than a general high-pass filter for extreme low-frequency content.
The Electro-Harmonix XO Micro Q-Tron is an envelope-controlled filter pedal in EHX's compact XO die-cast format, derived from the classic Mu-Tron III design. Playing dynamics drive the filter: harder picking produces a wider, more dramatic frequency sweep for an auto-wah response. Drive and Q controls set input sensitivity and resonance; a three-position mode switch selects Low Pass, Band Pass, or High Pass filtering. The XO format presents it in a rugged, compact enclosure.
