The Hard Bopper, developed in collaboration with renowned jazz harmonicist Toots Thielemans, is designed to stand out with an edge when played in the context of a full band. Heavy, chrome plated reedplates and extra large reeds give this 12-hole chromatic greater volume and a more aggressive sound than other models. Each Hard Bopper is serial numbered and carries a signed letter of quality assurance from Toots, who says that 'your instrument will receive the same attention as mine.' Specifications: 12 holes, 48 reeds, Key: C, Length: 5 5/8 inches
