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.65% — moderately similar

The DOD Envelope Filter 440 is a classic analog envelope filter and auto-wah pedal originally produced by DOD Electronics in 1977, delivering pick-attack-responsive filter sweeps with Sensitivity and Range controls. The DOD 440 became a widely used auto-wah with players including Jerry Garcia, who used it on the Grateful Dead's recordings. Later reissued under the DigiTech/DOD brand. An important pedal in envelope filter history.
The Electro-Harmonix Micro Q-Tron is a compact analog envelope filter, condensing EHX's classic Q-Tron auto-wah circuit into a smaller pedalboard-friendly enclosure. It tracks playing dynamics to automatically sweep a resonant filter, producing funky, vocal-like auto-wah textures without needing an expression pedal, driven purely by how hard the player picks.
