With the E.W.S. Fuzzy Drive Fuzz/Distortion Effect Pedal it is simple to get classic fuzz tones with some distortion or get a fuzz boost with its 3 easy knobs. This is not the one-trick pony that most have come to expect of "traditional" fuzz pedals. The Gain knob determines how hard the signal gets clipped so the more you crank on the Gain the more fuzz you will have. The Tone knob controls the harshness of the fuzz. Simple. Yet you will be completely surprised at how many fuzz tones you will get with this one little box.
