Until now, harmonicas just weren't made for blues. For one thing, they didn't last. After two or three blues sessions it was tough to get a good sound. The punishment of blues wailing often caused the reeds to lose pitch and flat out.
Now you've got the blues harp. With a new kind of reed system. And you can get a great blues sound with a minimum of effort.
The Blues Harp is a 10 hole/20 reed harmonica with a wood comb.
