Chicago's Daredevil Pedals fuzzified the Nashville atmosphere with killer and unique twists on several '60s fuzz circuits. But the Atomic Cock, which is essentially a wah circuit with a gain control and wah pot controlled via a standard pot and knob generated some of the nastiest and most distinctively tones at the show. Super versatile, hand built and just 130 bucks, it's one of the best deals at Sunmer NAMM too.
