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 whammy bar, which incorporates a heavy gauge coil spring for extreme durability. Players love the sensitivity of the buttery fret buttons on the fast-action neck, and its 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 strum bar has been tuned for a tighter feel and a more precise response, and all Guitar Controllers are made of environmentally friendly materials, which have passed the stringent RoHS standard set forth by the European Union.
