Independent shopping perspective
Neutrino V2 is a compact opto-coupler envelope filter, also known as an auto-wah. Its selected opto-couplers are described as smooth and vowel-like, while three filter ranges, two sweep directions, two frequency-center ranges, and Peak control provide several ways to shape the effect. Keeley’s voltage-doubler design is intended to maintain high headroom. The pedal is positioned for players seeking vocal-style filter sounds in funk, rock, alternative, or jam-oriented parts.
