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.66% — moderately similar

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 Diezel Zerrer is a two-channel high-gain preamp pedal from the German boutique amplifier builder, designed to deliver the character and feel of a Diezel amplifier front end in a compact pedal format. Both channels provide independent gain, bass, middle, and treble controls alongside a shared presence and master volume section. Channel 1 delivers clean-to-crunch tones while Channel 2 delivers the high-gain British metal character that defines Diezel amplifiers. The Zerrer can be used directly into a power amplifier or effects return, making it a complete preamp solution. Widely used in high-gain rock and metal rigs.
