If you want to play your instrument wirelessly without having to operate expensive and complex radio systems, you can use the practical Boss WL-20L radio system. Consisting of a compact transmitter for the instrument and a matching receiver, Auto Wireless Connection determines the ideal connection in any wireless environment so that the signal is always transmitted clearly and without interruption to standard amplifiers or effects devices. The WL-20L is specially designed for use with instruments with preamplifiers, such as electro-acoustic acoustic guitars, electric guitars and basses with active pickups or active electronics. Last but not least, the battery-powered WL-20L system with a maximum runtime of up to 12 hours offers enough power for longer gigs and sessions.
