The Hammer Jammer from Big Walnut Music is certainly one of the most interesting guitar add-ons I've seen in a while. As to what it does, the clue is in the name; it more or less converts your guitar into a hammer dulcimer, adding a whole new palette of sounds to the instrument. I think the above video illustrates quite nicely what it's all about.
