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.36% — somewhat different

The Fortin Amplification 33 is a gain boost and preamp pedal from Canadian boutique metal gear specialist Fortin Amplification, designed specifically to tighten, enhance, and drive high-gain amplifiers and distortion pedals for modern metal applications. The 33 adds gain and high-frequency definition to the guitar signal, producing a tighter, more articulate attack on distorted amplifiers and helping single-notes cut through the dense low-end of heavy metal. Jeff Loomis, Mark Holcomb, and other technical metal players have used the Fortin 33 to push their amplifier front ends for tighter, more defined high-gain tones.
The Keeley Filaments is a high-gain distortion pedal from Keeley Electronics delivering tight, focused, harmonically rich saturation suited to modern rock and metal applications. The circuit provides powerful gain with controlled low-end tightness and mid-presence for note definition in dense playing contexts. The Filaments is positioned as Keeley's primary high-gain distortion offering, providing the saturated, cutting character needed for modern heavy music without the loose, unfocused quality of some fuzz-based high-gain designs.
