Boss WL-50 Wireless Pedal Board System

Boss makes going wireless easy! Set the WL-50 dock in your pedalboard, plug the transmitter into your guitar, and hone your sound with selectable cable tone.

With the Boss WL-50, it's never been easier to bring wireless freedom to your pedalboard. Driven by BOSS technology, and part of the WL-20 wireless system family, the WL-50 delivers premium sound and a plug-and-play experience that eliminates all the hassles normally associated with wireless systems. The stompbox-sized receiver fits right alongside your other pedals, and includes a docking port for charging the transmitter and automatically setting the best wireless connection. There's even a handy DC output, allowing you to distribute power to multiple pedals on your board.

Once you experience the wireless independence provided by the WL-50, you'll never go back to using a standard cable again! Setup is quick and simple, and 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.

Equipped with the same high-performance wireless tech found in the WL-20 and WL-20L, the stompbox-size WL-50 features an integrated transmitter dock, two cable tone simulation options, and a DC output for distributing power to one or read more more pedals.
