The BOSS WL-20L is a wireless system for electric guitarists and other electronic musicians. It provides easy operation through its plug-and-play user experience. Simply plug the included WL-T transmitter into your guitar or line-level instrument (keytar, digital wind instrument, etc.), and plug the receiver into your amplifier, first pedal in the chain, or pedalboard input; or if you are using a line level device, plug into a mixer or PA. Now, you are free to roam up to 50' away from your amp without worrying about dragging gear, tripping up your bandmates, or accidentally unplugging yourself.

The BOSS WL-20L is a wireless system for electric guitarists and other electronic musicians. It provides easy operation through its plug-and-play user experience. Simply plug the included WL-T transmitter into your guitar or line-level instrument (keytar, digital wind instrument, etc.), and plug the receiver into your amplifier, first pedal in the chain, or pedalboard input; or if you are using a line level device, plug into a mixer or PA. Now, you are free to roam up to 50' away from your amp without worrying about dragging gear, tripping up your bandmates, or accidentally unplugging yourself.


The receiver automatically finds and sets the optimal wireless connection with the transmitter, selecting among 14 channels to do so, and operating over the carrier frequency of 2.4 GHz. At 2.3 ms, latency shouldn't be an issue. A USB charging cable is included, with which you can charge both the receiver and transmitter. To do this, plug the transmitter into the receiver, connect the charger to the DC-in port, and both units will be charged in around 4 hours. From there, you'll get approximately 10 hours of continues playing time.

This model differs from the WL-20 by not offering cable-tone simulation. Without the high-freqeuncy roll-off that mimics the capacitive effect of 10' guitar cables, the system is well suited for instruments with active pickups and onboard preamps, or line-level devices.

Proprietary Boss Technology

Equipped with the Katana-Air's wireless technology, the WL-20L delivers quality sonics with a wide dynamic range. Channel selection is handled automatically to ensure rock-solid audio performance with no drop-outs. With a latency of just 2.3 ms, you'll always enjoy great playing feel with no lag. 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 Rock

A WL-20L 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 an amp.

Automatic Wireless Setup

With the WL-20L, 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 many smartphones and tablets. The transmitter and receiver can also be charged separately, and a micro-USB cable is included for charging.

Built for Active Pickups or Line-Level Devices

Whereas the similar BOSS WL-20 system provides a cable tone simulation, the WL-20L does not. This makes it a better 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. The WL-20L also works with passive pickups if you don't need the subtle treble roll-off provided by cable tone simulation.
