The Keeley Neutrino V2 and the MXR CAE Wah are both pedals sharing smooth, mid-forward. The Keeley Neutrino V2 leans dynamic.

Similarity
citedBlended 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.

Description

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.

The MXR CAE Wah (Custom Audio Electronics MC404) is a Bob Bradshaw-designed dual-inductor wah with two voices and a boost, prized for a wide, vocal sweep and pro-grade build. Used by Eric Gales and Kim Thayil, it offers selectable inductors for different sweep characters plus a clean boost, suited to rock, blues and metal lead. It is a versatile, high-quality wah for serious players.
