No desire to read through thick instruction manuals and then carry out hours of adjustments? The Line 6 Relay G10 is the first true Plug and Play Wireless System for Guitar / Bass. Simply take the receiver from the built in docking station and plug it in the guitar and go! The transmitter is activated automatically when inserted into the socket of the guitar, the level is adjusted automatically, and a free channel is searched. The transmitter has a built-in lithium battery and is charged via the docking station. The battery life is about 8 hours (200 hours standby time). Can't get much easier!
