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.37% — somewhat different

The Airis Effects 51-Filthy is a tight, articulate high-gain preamp pedal from the Ontario, Canada-based boutique builder founded by Richard Seidlitz in 2014, voiced somewhere between a block-letter EVH 5150 and a Diezel Hagen, delivering crunchy, saturated distortion without losing note definition even at aggressive gain settings. Handbuilt in small runs and backed by a two-year warranty, it represents Airis's focus on high-gain metal and hard rock tones within a boutique pedal format, aimed at players wanting studio-quality amp-in-a-box distortion rather than a simple fuzz or overdrive circuit.
The Keeley Filaments is a high-gain distortion pedal from Keeley Electronics delivering tight, focused, harmonically rich saturation suited to modern rock and metal applications. The circuit provides powerful gain with controlled low-end tightness and mid-presence for note definition in dense playing contexts. The Filaments is positioned as Keeley's primary high-gain distortion offering, providing the saturated, cutting character needed for modern heavy music without the loose, unfocused quality of some fuzz-based high-gain designs.
