WIRELESS FREEDOM MADE EASY
Have you always dreamed about going wireless with your instrument, but were put off by the complicated setup, tone loss, and bulky adds-ons? If so, the WL-20 series is for you! Driven by new lightning-fast BOSS tech, these ultra-compact music tools deliver premium sound and plug-and-play operation that completely eliminates all the hassles normally associated with wireless systems.

Once you experience the easy wireless independence provided by the WL-20 series, 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 Technology
Equipped with high-performance BOSS wireless technology that debuted in the Katana-Air wireless guitar amp, the WL-20 series delivers exceptional sound quality with 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 drop-outs. And with ultra-low latency of just 2.3 ms, you’ll always enjoy 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.*

*Environmental conditions may affect the actual number of simultaneous systems available.

Plug In and Rock
A WL-20 system is literally 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 Setup
With the WL-20 series, 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 USB
When 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.

WL-20: Built-In Cable Tone Simulation
If 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.

WL-20L: No Cable Tone Simulation
The WL-20L model is functionally identical to the WL-20, with the exception that it eliminates cable tone simulation. This makes it the best choice for instruments where cable capacitance has little or no effect on the tone, such as an acoustic/electric guitar with an onboard preamp, a guitar or bass with active pickups, or a line-level device like a keytar or Roland’s Aerophone digital wind instrument. The WL-20L also works great with passive pickups if you don’t need the subtle treble roll-off provided by cable tone simulation.

WL-50: A BOSS Wireless System for Your Pedalboard
If you’re looking to bring wireless freedom to your pedalboard, check out the WL-50. 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 more pedals.
