I do not recommend buying the harmonics of the Hohner Super 64X Performance. It is much easier to play, in terms of breathing, on the harmonics of the Hohner ACE-48! Compared to well-known brands, the harmonics of the Hohner Super 64X Performance cannot compete with the Suzuki SC-64 and SC-56 slider harmonicas. And these harmonics are more than 40 years old !!! If you want to have a Hohner chromatic harmonica, buy a Hohner ACE-48 harmonica, but only in a good store, For example Sam Ash! Sam Ash has a great service and a full refund! Sam Ash can be trusted !!!
