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

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)

Reliable and quality audio

Extremely compact, the WL-20 fits snug into your guitar right out the way without 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 sound.

Cable sound recreation

The WL-20 has the option to replicate the capacitive sound created when using a 10-foot cable connection, which works especially well paired with passive pickups. The result is a warm tone with a slightly rolled-off treble frequency.

I have an old Stageclix wireless which is superb but prob on its last legs and getting replacements seem to be tricky when I search on the web. So when I checked the specs the WL-20 seemed ideal - compact form factor, no electric connection needed for the receiver, easy charging via USB, and slots in perfectly including into the recessed input of a Dingwall Combustion bass- this is important as both pieces have a small 'pressure button' switch that activates the system when plugged in, very convenient, and there are appropriate displays to indicate connection and battery aspects. The battery life is excellent on paper, and I tried this at rehearsals - very easy to set, and frankly with a 2.3ms lag time on paper one would have to be a bat to hear any difference! No noticeable change in sound quality at all. Very pleased with this and now time to take it out on stage.

Typical excellent Boss quality, does a great job with amazing sound quality and good range I can’t fault it at this price.

It’s easy to setup, works very well and it’s very convenient to be wireless. It’s expensive compared to ordinary cables though and it won’t fit in some recessed jack sockets.
