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 Acorn Amplifiers Solid State Preamp reimagines the company's original Solid State Amp/Preamp pedal, itself built around the same TDA-series class-AB power amp circuitry found in the vintage Peavey Decade, an unassuming solid-state practice amp that gained cult status as Queens of the Stone Age's Josh Homme's self-described secret weapon. Where the original pedal included two output jacks and a toggle to use it as either a standalone 10-watt amplifier or a pedalboard preamp, this slimmed-down preamp-only version drops the power amp stage entirely for a smaller, more pedalboard-friendly enclosure at a lower price, running on 9 to 18 volts DC with true bypass switching and foot-switchable Normal and Saturated channels replicating the Decade's wiry cleans and tightly coiled, aggressive gain.
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.
