OctaHarp Master

The J.A. Custom OctaHarp Basic Harmonica has unique features, including its own serial number. The harmonica features expert reed work for a loud & warm sound. The OctaHarp is designed by Brendan Power and it is unique because it combines two diatonic harps an octave apart to make one compact instrument with the big double-reed octave sound.
