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.51% — moderately similar

The Horizon Devices Apex Preamp is a Misha Mansoor-designed high-gain preamp/distortion (built by MXR) that works in front of amps, into power amps, or direct to a board or interface. It delivers tight, aggressive, modern metal gain with a flexible EQ and an Attack control to tighten low end for down-tuned, djent-style playing. It suits progressive and modern metal players wanting amp-like high gain from a pedal.
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.
