The OctaHarp is designed by Brendan Power, he 3D prints the front piece. It is unique because it combines two Marine Band harps an octave apart to make one compact instrument with the big double-reed octave sound. Another great feature is that the OctaHarp has the same hole spacing as a regular Marine Band, all other octave tuned harmonicas has the same hole spacing as the Chromatic harmonica.
