NUX B-2 Wireless Guitar System

NUX B-2 works like a guitar cable but offers wireless freedom. The Transmitter & Receiver both use built-in long-life batteries which can run for up to 20 hours (up to 6 hours of continuous playing time per charge). When you're not playing, B-2 enters Sleep Mode to extend battery life up to 20 hours. And when it's time to recharge simply connect the USB cable (included w/ package) to the transport-coupled Transmitter/ Receiver.
