Based upon Johnson's favorite fuzzes which Dunlop has reproduced beautifully. Personally my favorite old school sounding fuzz pedal. The only complaint I could see someone having about this pedal is that is a one trick pony; however, a great pedal is a one trick pony, that is why people have so many different boxes. Basically if it's good enough for Eric Johnson, it's good enough for me! Give one a shot today, you may just walk out with it. *Hands on review by Christopher M. from store 57 in Indianapolis.
