Truly a master's instrument, the Hohner Super 64X Performance Chromati Harmonica features a sleek design and a range of innovative features. The VarioSpring System permits individual adjustment of slide spring tension. The SilentSlide is exceptionally airtight and almost completely noiseless in operation. The loud, double-thick reed plates are mounted with screws, without contact to the covers, reducing reed wear and making basic maintenance much simpler. The M758601 will take you to new performance pinnacles.
