The GB 40 guitarbug is probably the easiest way to turn a guitar, bass, or portable keyboard into a wireless instrument.
The FlexJack swivel jack plug will mate with any type of output jack and is spring loaded to hold the GB 40 securely against the instrument. In addition, the GB 40 is so small it is almost invisible and won't be in your way while playing. Since the GB 40 sits right on top of the instrument's output jack, the noiseless on/mute/off switch and gain control are always within easy reach. Integrated charging contacts allow you to charge the battery quickly and easily on the optional CU 40 charging unit, without having to remove the battery.
