The Warm Audio Foxy Tone Box is a recreation of a '70s vintage fuzz pedal used by artists like Billy Gibbons and Peter Frampton. The Volume, Sustain, and Fuzz knobs give you classic mellow fuzz tone to full mayhem. The switch on the front engages a pronounced octave effect. This pedal is in very good condition and comes with the original box...it is also fuzzy to the touch!
