As has now become the trademark for Guitar Hero games, with every new installment comes a new controller variation, and Warriors of Rock isn't going to be the one to buck the trend.
While the Guitar Hero 3 Les Paul controller introduced changeable faceplates to allow the player to customize it, the Warriors of Rock guitar goes one step further, and features an entirely removeable body, which can be changed to suit the player.
The body itself is made of two removable wings, which clip onto the main neck of the guitar - hopefully, the bodies will also be symmetrical, to allow for construction of left-handed guitars.
All the electronics for the controller are held in one single construction - which will hopefully go some way to improving the controller's reliability, as the neck joint on the previous guitars had a habit of working its way loose after a while, meaning that it sometimes stopped registering button presses. If you're in a particularly strange mood, it'll even be possible to remove the body entirely, and just play with the neck/strum bar section.
The other noticeable difference between the Warriors of Rock guitar and the World Tour/Guitar Hero 5 guitar is the omission of the touch strip on the neck, but did they just forget to include it on the model, or are they getting rid of it altogether?
