The Hohner M564106P-A is the product code for the Hohner Pro Harp harmonica in the key of A. This harmonica, often nicknamed the “Rock Harp,” is a member of Hohner’s MS (Modular System) series. It is known for its rugged design and powerful, focused tone, making it a popular choice for rock and blues musicians. It features a durable, moisture-resistant ABS plastic comb and black-lacquered stainless steel covers without side vents, which contributes to its loud projection. The key of A is particularly useful for playing in the second position (cross harp) in the key of E.
