    Product Description

    This is wireless systems made easy. Boss introduce the WL-20L, which you simply need to plug in and get playing. No frequency changing to do, just really simple, intuitive tech to give you peace of mind. 

    Key Features

    • Plug-and-play wireless systems for guitar, bass, and other electronic instruments
    • No complicated setup required—simply dock the transmitter and receiver together for about 10 seconds to set the optimum wireless connection
    • Newly developed BOSS technology delivers premium audio performance with rock-solid stability, ultra-low latency (2.3 ms), and 50-foot/15-meter range (line-of-sight propagation)*
    • Built-in rechargeable batteries provide up to 12 hours of continuous playing time**
    • Simple charging with a standard USB adaptor (5 V/500 mA or greater)
    • Cable tone simulation reproduces the natural capacitive effect of a 10-foot/3-meter guitar cable (WL-20 model only)
    • Spare WL-T Transmitter available separately
    • Compatible with active pickup bass and guitars

    Reliable and quality audio

    Extremely compact, the WL-20L fits snugly into your guitar out the way, not disrupting any playing comfort. Simply dock the transmitters to set up connection quickly and charge for up to 12 hours of playing time. 

    Don't expect any signal drop-outs as the Boss wireless system works in a 2.4 GHz frequency for great audio. Ultra-low latency also prevents a lag between playing and the amp producing the sound. The only difference between the WL-20 and the WL-20L is the lack of tone cable simulation, which is ideal anyway for acoustic guitars with a preamp on board, as the capacitance won't change the tone.

    Mr Campbell Berrie11th Apr 2021

    Love the freedom of being wireless. Easy to use and no distinguishable loss of performance. Initial downside, wouldn't work with Squier 50's vintage Telecaster, but addition of steel washer solved that problem.
