Simply dock the transmitter to the receiver for approximately 10 seconds to automatically establish the optimal wireless connection. BOSS's proprietary wireless technology delivers high-quality sound and a stable connection with ultra-low latency of just 2.3 ms (transmission range: 15 m). *Varies depending on location and conditions. When fully charged, the transmitter can be used for up to approximately 12 hours and the receiver for approximately 7 hours. Easily rechargeable with a universal USB adapter (5V/500mA or higher). Cable tone simulation reproduces the natural change in sound quality that occurs when using a 3m guitar cable. Spare transmitter WL-T sold separately. The WL product line from BOSS makes it easy and convenient for every musician to enjoy wireless independence wherever they play. Plug-and-play wireless virtual cable for guitar, bass, and other electronic instruments. No complicated setup required—simply dock the transmitter (to the guitar) and receiver (to the amp) 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). The transmission range may vary due to local conditions. A full charge provides 12 hours of time for the transmitter and 10 hours for the receiver. The BOSS WL-20 is a simple and reliable wireless system for guitar, bass and other electronic instruments. After plugging in the transmitter and the receiver, they'll automatically connect to each other in about 10 seconds. Thanks to the newly-developed technology, superior audio quality and ultra-low latency is assured. That means you can concentrate on playing your instrument while enjoying complete freedom.The WL-20: Cable Tone SimulationThe WL-20 is a good choice for instruments with passive pickups, and the cable tone simulation feature gives you the same capacitive effect as you get when you connecting your instrument using a cablem reducing the trebles and giving you a warmer sound. The WL-20 is easy to charge using the included USB cable and fully-charged batteries will power the receiver for approximately 10 hours and the transmitter for approximately 12 hours.
The BOSS WL-20 is a plug-and-play wireless system designed for guitarists, bassists, and electronic instrument players seeking freedom from cables. Its key benefit is an incredibly simple setup and reliable, low-latency wireless connection. A potential caveat is the built-in cable tone simulation, which may not be ideal for all instrument types. This system offers high-quality sound, stable connectivity, and extended battery life, making wireless performance accessible to all musicians.

FAQs
How do I pair the WL-20 transmitter and receiver?
Pairing is automatic. Simply plug the transmitter into your instrument and the receiver into your amplifier or pedal. Then, dock the transmitter onto the receiver for about 10 seconds. They will establish the optimal wireless connection automatically.
What is Cable Tone Simulation on the WL-20?
Cable Tone Simulation replicates the natural tonal effect of using a standard 3-meter (10-foot) guitar cable. It slightly reduces treble frequencies, providing a warmer sound that is particularly beneficial for instruments with passive pickups.
How long does the battery last and how is it charged?
The transmitter can run for up to 12 hours on a full charge, and the receiver for up to 10 hours. Both can be charged simultaneously by docking them together and connecting a standard USB adapter (5V/500mA or higher).
Can I use multiple WL-20 systems in the same space?
Yes, up to 14 BOSS wireless systems can operate simultaneously in the same location without interference, thanks to BOSS's advanced wireless technology.
What is the difference between the WL-20 and WL-20L models?
The main difference is the Cable Tone Simulation. The WL-20 includes this feature for a warmer tone with passive pickups. The WL-20L omits this feature, making it a better choice for instruments where cable capacitance has little effect, such as those with active pickups or preamps.
What is the maximum wireless range?
The transmission range is up to 15 meters (approximately 50 feet) under optimal line-of-sight conditions. This range may vary depending on environmental factors and obstructions.
Does the WL-20 work with active pickups?
Yes, the WL-20 system will work with instruments featuring active pickups. However, the Cable Tone Simulation feature is designed for passive pickups and may alter the intended tone of active pickups. The WL-20L model is recommended if you do not need or want cable tone simulation.
Troubleshooting
No sound or intermittent connection
Ensure both transmitter and receiver are fully charged. Re-dock the transmitter and receiver for 10 seconds to re-establish the automatic connection. Check that the transmitter is securely plugged into the instrument and the receiver into the amp/pedal. Ensure you are within the 15m transmission range.
Low volume or weak signal
Check the instrument's volume and the amplifier/interface's gain settings. Ensure the receiver is properly connected and powered. If using the WL-20 model with an instrument that does not benefit from cable tone simulation (e.g., active pickups), try the WL-20L model for a cleaner signal.
Battery not charging
Verify that the USB adapter meets the 5V/500mA or higher specification. Try a different USB cable and power adapter. Ensure the charging contacts on both units are clean and free of debris.
Sound is too trebly or lacks warmth
If using the WL-20, this may be due to the Cable Tone Simulation. If you prefer a brighter sound or are using active pickups, consider the WL-20L model which lacks this feature. Adjust your instrument's tone controls or amplifier EQ as needed.
Pros and Cons
Pros
Extremely easy to set up and use, requiring no technical knowledge.
Delivers a stable and reliable wireless connection with minimal latency.
Offers excellent battery life for extended playing sessions.
The Cable Tone Simulation feature provides a familiar, warm tone for passive pickups.
Compact design makes it unobtrusive on instruments and pedalboards.
Provides true wireless freedom without sacrificing sound quality.
Cons
Cable Tone Simulation might alter the tone of instruments with active pickups or preamps.
Transmission range can be affected by environmental conditions.
Requires a separate USB adapter for charging (not always included with devices).
Only one spare transmitter (WL-T) is sold separately, limiting options for multiple instruments.
No dedicated display on transmitter or receiver for status information.
Setup, Compatibility & Care
Setup:
Plug the transmitter into your instrument's output jack.
Plug the receiver into your amplifier, pedalboard, or audio interface's input jack.
Dock the transmitter to the receiver for approximately 10 seconds. The units will automatically pair.
Once paired, undock the units and power on your instrument and amplifier/interface. The wireless connection is now active.
Compatibility:
Instruments: Ideal for electric guitars, bass guitars, and other electronic instruments with standard 1/4-inch output jacks.
Pickups: Best suited for instruments with passive pickups due to the Cable Tone Simulation feature. It can also be used with active pickups or instruments with preamps, but the cable simulation effect will be less relevant or may alter the intended tone.
Charging: Requires a standard USB adapter (5V/500mA or higher) and a USB cable (often a Micro USB to USB-A cable is included).
Care:
Cleaning: Wipe both the transmitter and receiver with a clean, dry cloth. Avoid using liquids or abrasive cleaners.
Storage: Store in a cool, dry place when not in use. Protect the connectors from dust and damage.
Battery Care: Fully charge the units before first use. Avoid exposing them to extreme temperatures, which can affect battery life and performance.
