Keeley Neutrino | Envelope Filter V2
Improved Note Tracking, Upgraded Components & Fresh New Look

The Keeley Neutrino V2 is an amazingly toneful and compact form of the classic opto-coupler envelope filter. The Neutrino takes your guitar playing and creates an automatic wah sound based on your pick attack! 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 particularly smooth, giving you an amazing vowel-like tone. The Keeley Neutrino gives you three filter ranges, two directions, two ranges for the frequency center and a Peak control. Keeley has engineered a power supply voltage-doubler so you maintain the highest headroom for your tone. An incredibly tough 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.
