Guitar The exciting new freedom v wireless guitar controller offers a 100 foot radius of auto- sense 2.4ghz wireless connectivity for up to 800 hours of play on one battery pack (4 aa batteries not included). It includes a patent-pending recessed start button, which prevents players from accidentally pausing the game, and a finely tuned, highly responsive chrome super whammy system whammy bar, which incorporates a heavy gauge coil spring for extreme durability. Players love the feather-touch sensitivity of the buttery fret buttons on the fast-action neck, and its smart bidirectional accelerator sensor allows players to simply "tilt upwards" the controller to enter the star power bonus mode of the game-instead of having to play the controller while raising the guitar vertically. The rocking rhythm strum bar has been tuned for a tighter feel and a more precise response, and all guitar mania controllers are made of environmentally friendly materials, which have passed the stringent rohs standard set forth by the european union.
