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.34% — somewhat different

The Fortin Amplification 33 is a clean boost pedal designed in collaboration with Fredrik Thordendal of Meshuggah, developed over two years to serve as a precision front-end tool for modern high-gain amplifiers. It delivers up to 22dB of clean boost that tightens low-end response, enhances pick attack articulation, and improves note separation in saturated, down-tuned amplifier contexts. Built in the United States with premium components and true bypass switching, the 33 includes a remote channel switching jack for hands-free amplifier channel control. Used by Thordendal in Meshuggah for the djent, progressive metal, and extreme rhythmic precision the band requires.
The Klon Centaur is a single-channel overdrive designed by Bill Finnegan and built in limited numbers between 1994 and 2008, now one of the most collectible and expensive guitar pedals ever made. It works by blending the dry guitar signal with a gain stage that uses germanium diode clipping and an internal voltage-boosting charge pump for extra headroom. The result is a clear, dynamic low to medium gain drive with strong clean headroom, crisp transients, and a gentle midrange lift that helps notes bloom and cut. Players use it as an always-on transparent boost or to push a tube amp into richer breakup, and it stacks well in front of other drives. Associated with Jeff Beck, John Mayer, Joe Perry, Nels Cline, and Warren Haynes, it suits blues, classic rock, and roots tones rather than heavy high-gain distortion.
