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.42% — somewhat different

The Keeley Klon Centaur-Style Overdrive is Keeley's take on the celebrated Klon Centaur transparent overdrive circuit, aiming for the same warm, touch-sensitive, harmonically rich push into an amp that made the original Centaur legendary and famously hard to obtain. It delivers the classic Klon-family clean-boost-to-mild-overdrive range, preserving pick dynamics and note clarity rather than imposing a heavy drive coloration.
The Vox Valvenergy Fuel Injector is a tube overdrive pedal built around Vox's Nutube technology, a genuine miniature vacuum tube adapted from vacuum fluorescent display components, giving it real tube harmonic character without a traditional tube's heat, bulk, or maintenance needs. It runs on standard 9V power with no separate heater or ventilation required, delivering dynamic, touch-responsive overdrive with the smooth, musical harmonic overtones associated with genuine tube circuits. It's part of Vox's Valvenergy line aimed at bringing authentic tube-driven dynamics into a compact, low-maintenance pedal format.
