zZounds, an online musical instrument retailer, is giving away one of Billie Joe's new signature Gibson ES-137 guitars that will also be hand-signed by the man himself. The guitar normally retails for $3,299.

The contest is open to residents of the U.S. (sorry, international folks) who are 21 or older, and requires only a valid email address for entry. A winner will be chosen at random on September 12. You can enter once on zZounds' contest page. Good luck!
