The Hohner 7545 CX12 Chromatic Harmonica has a 1-piece housing that provides warm, round tone. A comfortable smooth mouthpiece, and nonslip cover surface make the 7545 a better handling harmonica. Back-mounting spring plate eliminates the need for mouthpiece and cover screws, providing optimal slide action and improvement in compressing. This gives quicker response, greater volume, and exceptional ease in note bending. The harmonica's 4 major parts can be disassembled and reassembled in seconds with no tools. Makes cleaning a snap.
