The new Blues Bender P.A.C. harmonica features Patented Acoustic Covers that are based on the design of the Marine Band Harmonica, which is the all-time favorite for serious harp players since 1896. The Blues Bender was designed primarily to make playing and note bending easy for entry level players. Originally patented by Jacob Hohner in 1897, the special shape of these covers increases the volume of air enclosed between the reeds and cover-plates which, when thrown into vibration and vented through the special side vents, allows for greater volume and projection. The Blues Bender P.A.C. features thicker than normal reed plates for a consistent tone. It is extremely airtight between the mouthpiece and the reed plates, allowing for easier note bending and making expressive playing easier. The Blues Bender P.A.C. allows everybody access to the bluesy notes needed to make any riff complete.
