The Keeley Neutrino V2 is an amazingly toneful and compact form of the classic opto-coupler envelope filter. Envelope filters or auto-wahs as they are often called, sound and react best when they are opto-coupler based. The opto-couplers used in the Neutrino are carefully selected and particularly smooth, giving you an amazing vowel-like tone.

The Keeley Neutrino offers 3 filter ranges, 2 sweep directions, 2 ranges for the frequency center and a Peak control. Keeley has engineered a power supply voltage-doubler so you can maintain the highest headroom for your tone, just like the classic pedal we're all inspired by. An incredibly robust build means it will last for many decades to come. Whether you're in a jam band or playing funk, the Keeley Neutrino V2 delivers incredible vocal-like tone.
