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.35% — 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 Donner Big Mouth is a multi-mode distortion pedal offering three distinct voicings, from a tight, natural low-gain crunch through a classic mid-gain crunch tone to an aggressive 80s-style high-gain metal voicing, giving players a range from rhythm crunch to searing lead distortion in one budget-friendly, true-bypass pedal. It suits budget-conscious players wanting an accessible distortion pedal that covers classic crunch through modern high-gain metal tones without premium pricing.
