  • Bahnson Overblow - II

The "Overblow Harp" was designed by cardiac surgeon, Dr. Henry Bahnson in 1990. The aim was to make the "missing notes" available for the average player on the diatonic harmonica-- that Howard Levy was hitting with great facility. He knew other notes were available on the ten-holer but the same tones were available by normal playing. The first overblow harmonica was hand-filed and the first batch of one hundred cost over $120 each to make. They have all been either sold or given away, and are currently very rare to find in circulation.
We have developed a more economical version with the same functionality as the original. This harp is based on a Hohner Special 20 and features a slide valve mechanism that, like training wheels on a kid’s bike, can make overblowing so much easier (10 times, Yerxa once said).
Project Status: Commercial prototype completed. Currently seeking investors or industrial partners.
