Customers who pre-order the guitar bundle with GameStop will receive exclusive Battle Axe guitar wings for the Guitar controller. The exclusive guitar wings will convert the standard controller into a ready-to-rock Battle Axe controller. The offer will come packaged separately and will be distributed when customers pickup the guitar bundle.

Guitar Hero: Warriors of Rock will be available at GameStop stores nationwide this September. For more information or to find a store near you, log on to www.gamestop.com.

Not an exceptionally cool pre-order item I suppose as it won’t really affect gameplay or add anything to the experience.
