From the folks at Keeley comes the Neutrino Envelope Filter, an Auto-Wah with a funky circuit that's been in the works for nearly a decade. A classic opto-coupler design adds richness and warmth to your signal, which is filtered based on the strength of your pick attack. Simple controls let you adjust your tone so you can get it just right for solo work or chords. The Direction Switch even lets you control the direction of your wah as an additional clever perk. Dial up the funk and "Let's Get It On" with the Keeley Neutrino.
