The J.A. Custom OctaHarp Master Harmonica has unique features, including its own serial number. The harmonica features expert reed work making it extremely loud and responsive. The OctaHarp moutpiece 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.
You can get your OctaHarp in any tuning you like. Most common tunings for Irish music is Easy Third, Paddy Richter, Solo and Richter. Check out the page called "Tunings" for more info. We tune your OctaHarp to 442hz equal temperament, that sounds best if you play with other melody instruments. However, we can accommodate your preference for an alternate temperament.
