The Hohner Chromonica 64 is an unusual harmonic because it has the capability to play an octave under middle C. Beyond that, it has a much better sound quality than many other harps out there, including the CX-12. It has round holes, which do tend to make it more comfortable to play than harmonicas with square holes. However, that is also one of the reasons why this harmonica is a bit higher priced than similar square-holed models. But the sound quality definitely makes this harmonica well worth the price. Not only that, but the slide is much better than other models, including the CX-12. Although, adjusting to the Hohner Chromonica 64 may be difficult for those who are switching over from diatonics for the first time.
Reeds may require replacement more often than some models
