"Guitar Hero World Tour" features another new controller known as the "Genericaster". Unlike previous guitar controllers, this is not modeled after a real guitar design, but resembles a Fender Stratocaster, hence its name. As well as a new shape, it features a longer, quieter strum bar, longer whammy bar, and repositioned start and select/back buttons. It also features a new, touch sensitive "solo section" on the neck. This is functionally similar to the "solo section" on "Rock Band" guitar controllers, but is not compatible with "Rock Band" games. Like the "Guitar Hero III" Les Paul controller, the PlayStation 3 version of the Genericaster connects via a USB dongle, which also acts as a two-port USB hub, while the Wii version connects to the Wii remote accessory connector and the Xbox 360 version connects via Microsoft's 2.4 GHz wireless technology. Also like the Les Paul, it features a detachable neck and customizable faceplates. This guitar was available separately, bundled with a "Guitar Hero World Tour" "guitar bundle" or "band bundle" (game, guitar controller, drum kit and microphone) or bundled with "". Like the Aerosmith Les Paul, the "Guitar Hero: Metallica" version features a custom ("Metallica" themed) faceplate. The guitar controller for "Guitar Hero 5" retains the same basic design as the "Guitar Hero World Tour" Guitar Controller, but with some minor alterations. The strum bar is rubberized, the nuts on the headstock are made from chrome rather than plastic and the "solo section" of the neck is molded differently and is now digital rather than analog. The guitar controller released for "" is, like the "World Tour" and "5" guitars, not based on a real guitar design. This controller differs from its predecessors however, in that it drops the touch-sensitive strip on the neck, and allows for complete replacement/customization of the body, rather than just faceplates as on previous controllers. "Guitar Hero Live" had a guitar controller with two rows of 3 buttons each. This renders the game incompatible with the older Guitar Hero controllers, as well as making the Guitar Hero Live controller incompatible with older games. The guitar controller for "Rock Band" is based on the "Fender Stratocaster". It features two sets of fret buttons, one for standard gameplay, one for solo sections.
