Airis Effects SPEC-Defier

Airis Effects · pedal

Airis Effects designed the SPEC-Defier as a follow-up to their well-received 51-Filthy preamp, aiming this time for a thicker, more Mesa Boogie Rectifier-style voicing rather than the tighter, more articulate character of its predecessor. Built by Ontario-based Richard Seidlitz, who founded Airis in 2014 with a focus on high-gain boutique pedals, the SPEC-Defier trades some of the Filthy's precision for a heavier, more saturated crunch and chug, giving players two distinct high-gain flavors within Airis's small but focused catalog rather than a single one-size-fits-all metal preamp.
