Wireless Freedom - Fast and Easy!
Have you always dreamed of playing your instrument wirelessly but were put off by complicated setups, tone loss, or bulky accessories? In that case, the WL-20 series is just right for you! Based on a new, ultra-fast Boss technology, these especially compact systems deliver high-quality sound with simple plug-and-play operation, so you never have to deal with the hassles of traditional wireless systems again.
Once you get used to the hassle-free wireless freedom of the WL-20 series, you’ll never long for a cable on your instrument again! Since you no longer have to worry about cable management, you can fully enjoy this new freedom while playing—whether at home, jamming with friends, or on the live stage. During soundcheck, you can monitor your tone from anywhere in the venue to find the perfect settings for your audience. Plus, you can interact better with your bandmates and make your stage performance even more dynamic and entertaining.
Extremely Fast Boss Wireless Technology
After the powerful Boss wireless technology was first used in the wireless Katana-Air guitar amplifier, the WL-20 series now benefits from outstanding sound quality and a wide dynamic range. The wireless systems operate in the 2.4 GHz frequency band and automatically find the optimal channel to ensure maximum stable audio transmission without dropouts. Thanks to the extremely low latency of only 2.3 ms, you won’t hear any timing delay while playing. Up to 14 Boss wireless systems can be used simultaneously in one room, allowing multiple musicians to enjoy wireless freedom at the same time.
(The actual number of simultaneously usable systems may vary depending on environmental conditions.)
Connect and Play
The WL-20 wireless system is as easy to use as a conventional guitar cable. The compact transmitter plugs into the instrument input of your instrument, while the matching receiver connects to a pedal or amplifier. That’s it!
Automatic Wireless Setup
With the WL-20 series, you won’t get lost in tricky channel setups. All you need to do is pair the transmitter and receiver for ten seconds. The WL-20 automatically handles the optimal wireless connection.
Easy USB Charging
When paired, the built-in batteries in the transmitter and receiver can be charged using a standard USB adapter (5 V / 500 mA or higher), which is also used for current smartphones and tablets. If needed, the transmitter and receiver can also be charged separately. A micro-USB cable is included.
WL-20: Integrated Cable Simulation
For guitarists and bassists with conventional passive pickups (the most common pickup type), the WL-20 model is the perfect choice. The receiver features an integrated cable simulation that reproduces the natural capacitive effect of a 3m guitar cable when used with passive pickups. This effect slightly attenuates the highs and delivers the warm sound of a wired instrument.

recently used at live performance outdoors, together with WL20L.
so far no problems. Set the WL-20 for the electric guitar and the WL20L for my Roland Fr8X V accordion.

After a tip from Kirstein, the two parts worked after several attempts.
Now the parts work, but let me down on stage??? Do not want to hope!

Only one thing is not quite as nice. The jack plug seems to me minimally longer than usual. Unfortunately, this has the consequence that the transmitter is pushed so far out of the socket with a few of my basses that the contact switch no longer reaches the edge of the socket. But I don't plan to plug the transmitter directly into the instrument anyway, but to use a short extension cable and then put the transmitter in the back pocket of my trousers. Then I do not have such a block on the bass :o)
So still full 5 stars, because the price is also very pleasant.
