The Hammer Jammer is a unique, key-hammering device for six-string guitar, which allows players to invent new finger-style patterns and percussive chords, and to play with blazing speed.  Hammering techniques available with the Hammer Jammer also provide a useful tool for players with limited finger flexibility.
