Used Keeley Neutrino Pedal

Add expressive funk and dynamic sweep to your rig with this used Keeley Neutrino envelope filter pedal in good condition. Powered by standard 9V DC (center-negative), it delivers touch-sensitive auto-wah tones with smooth, musical response. Simple controls let you dial in filter direction, sensitivity, and peak for everything from subtle quack to bold, synthy vowel sounds. True-bypass switching keeps your core tone intact when disengaged, making it a versatile pedalboard staple.
