The Bushman Knittlinger is loud and lively, quick and nimble, and very easy to play. In fact, it takes less air than any double reed harmonica ever made! This 10-hole, 40-reed harmonica is remarkably easy to play, requiring less air than any double reed harmonica ever made while producing a huge, accordion-like sound. Featuring the traditional Auto Valve note layout with keys in Low A, Low Bb, Low C, and Low D, the Knittlinger is loud, lively, and incredibly responsive. Its durable plastic comb won't warp, and the comfortably thin, rounded mouthpiece allows for lightning-fast playing—it responds as quickly as you can play it. This is the best playing Double Reed Harmonica in the world!
