Review Summary

Rated 4 out of 5

Great for clutter and cable free spaces

Good tone and battery life. The channel selection process is simple and intelligent. Be wary of surrounding 2.8ghz devices, the mileage may vary, but it has worked well for me in a 2.8ghz saturated space.

About Boss WL-20

Overcome the limitations of wired instruments with the WL-20 Wireless System, designed for musicians seeking freedom, ease of use, and superior sound quality. This system, powered by Boss's innovative technology, offers a compact solution that eliminates the complexities typically associated with wireless setups. The WL-20 series is not just a wireless system; it's a revolution in the way you play, offering unprecedented mobility and interaction during performances.

The WL-20 series is equipped with Boss's high-performance wireless technology, first introduced in the Katana-Air wireless guitar amp. This technology ensures exceptional sound quality and a broad dynamic range. Operating in the 2.4 GHz frequency band, the system automatically selects the optimal channel, guaranteeing stable audio performance without any drop-outs. With an ultra-low latency of just 2.3 ms, you can expect a seamless playing experience with no lag.

The WL-20 system supports simultaneous use of up to 14 Boss wireless systems in one space, making it an ideal choice for band performances or jam sessions. The plug-and-play design is as simple as using a standard guitar cable. The compact transmitter plugs into your instrument, while the matching receiver plugs into a pedal or amp, and you're ready to rock!

Setting up the WL-20 series is a breeze. There's no need to fiddle with channel settings; just dock the transmitter and receiver together for about 10 seconds to automatically establish the optimal connection. Charging is equally straightforward, with the built-in batteries in the transmitter and receiver able to be charged together using a standard USB adapter (5 V/500 mA or higher). A micro USB cable is included for your convenience.

One of the standout features of the WL-20 series is the built-in cable tone simulation. This feature is particularly beneficial for musicians using guitars or basses with standard passive pickups. The system replicates the natural capacitive effect that occurs when using a 10-foot/3-meter guitar cable with passive pickups, subtly rolling off the treble to deliver the warm tone you're accustomed to with a regular cable.

In summary, the WL-20 Wireless System offers a seamless transition from wired to wireless, maintaining the tone and feel you love while giving you the freedom to move and perform without restrictions.
