Driven by new lightning-fast BOSS tech, these ultra-compact music tools deliver premium sound and plug-and-play operation that eliminates all the hassles normally associated with wireless systems. Once you experience the easy wireless independence provided by the BOSS WL-20 Digital Wireless Guitar System, you’ll never go back to using a standard cable again. With no worries about cable management, you’re able to move about freely while playing at home, jamming with friends, and performing on stage. During sound check at a gig, you can listen to your tone out front and dial in the best sound for your audience. And with the ability to roam and interact with other musicians, your live shows will be more dynamic and entertaining than ever.Lightning-Fast BOSS Wireless TechnologyEquipped with high-performance BOSS wireless technology that debuted in the Katana-Air wireless guitar amp, the WL-20 delivers exceptional sound quality with a wide dynamic range. Working in the 2.4 GHz frequency band, the optimum channel is set automatically to ensure rock-solid audio performance with absolutely no dropouts. And with ultra-low latency of just 2.3 ms, you’ll always enjoy a great playing feel with no lag whatsoever. Up to 14 BOSS wireless systems can be used simultaneously in one space, allowing multiple musicians to enjoy wireless freedom at the same time.Plug In and RockA WL-20 system is as simple to use as a standard guitar cable. The small transmitter plugs into your instrument, while a matching receiver plugs into a pedal or amp. That’s it!Automatic Wireless SetupWith the WL-20, there’s no fiddly channel setup required. Just dock the transmitter and receiver together for about 10 seconds to automatically set the optimum connection.Easy Charging via USBWhen docked, the built-in batteries in the transmitter and receiver can be charged together with a standard USB adaptor (5 V/500 mA or higher), the same type used with the latest smartphones and tablets. The transmitter and receiver can also be charged separately, and a micro USB cable is included for charging.Built-In Cable Tone SimulationIf you play a guitar or bass with standard passive pickups (the most common pickup type), the WL-20 model is probably your best choice. It includes built-in cable tone simulation, which reproduces the natural capacitive effect that’s introduced when using a 10-foot/3-meter guitar cable with passive pickups. This effect rolls off the treble very slightly, giving you the warm tone you’re used to hearing with a normal cable.
