With this model Hohner sets a new benchmark. In close cooperation with leading players, Hohner have once again revolutionized the chromatic harmonica to redefine the instrument in the 21st century - a real ACE up your sleeve! ACE stands for Acoustic Coupling Elements, removable inserts with which you can adjust tonal color and weight distribution of your ACE 48 to your personal taste. In addition, the new VarioSpring system permits adjustment of slide spring tension to suit your playing style. These two features represent genuine innovations which have never previously been available in a series built harmonica and are exclusive to HOHNER. The ACE 48 also offers unparalleled playing comfort thanks to the all-new ergonomic cover and mouthpiece design. It is delivered equipped with brass coupling elements, with the option of purchasing pearwood elements as add-ons. With the ACE 48, we continue to set new standards in chromatic harmonica design.
