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 Fairfield Circuitry Long Life is a single-band resonant parametric EQ pedal built around a second-order state-variable filter core. The Tilt control sweeps the filter continuously from low-pass through band-pass to high-pass. Freq sets the center frequency; Q controls the resonance peak height; Volume sets overall output. This combination produces EQ curves ranging from subtle tonal smoothing to dramatic, resonant frequency emphasis. Designed for stacking before or after other pedals to add tonal emphasis or de-emphasis.
The Keeley Neutrino V2 is a compact, all-analog opto-coupler envelope filter and auto-wah that creates a touch-sensitive wah sound from your pick attack. Hand-selected opto-couplers, described as higher grade than those in vintage originals, give it a smooth, vowel-like, vocal tone. It offers three filter ranges, two sweep directions, two frequency-center ranges, and a Peak control for shaping resonance, with true bypass to avoid tone suck. It suits funk, fusion, and expressive playing where dynamic filter movement adds vocal character to lines. Simple to dial in for a satisfying auto-wah, it is a small, focused envelope filter, though some players find its output can sound thinner than they expect at certain settings.
