Product Information
Full details
The BOSS WL-20L is a plug-and-play wireless system designed for guitarists, bassists, and other electronic musicians seeking freedom from cables without compromising sound quality. Its key benefit is its effortless setup and reliable, low-latency performance, making it ideal for instruments with active pickups or built-in preamps. A potential caveat is its lack of cable tone simulation, which might be missed by players using passive pickups who prefer that specific tonal characteristic.

FAQs
What is the main difference between the WL-20 and the WL-20L?
The primary difference is that the WL-20 includes cable tone simulation to replicate the sound of a short instrument cable with passive pickups, while the WL-20L does not. The WL-20L is recommended for instruments where cable capacitance has little impact on tone, such as those with active pickups or built-in preamps.
How long does the battery last on a full charge?
A full charge provides approximately 12 hours of continuous use for the transmitter and 10 hours for the receiver.
How do I charge the WL-20L system?
You can charge both the transmitter and receiver by docking them together and connecting them to a standard USB adapter (5 V/500 mA or greater) using the included micro USB cable. They can also be charged separately.
What types of instruments is the WL-20L best suited for?
It is ideal for guitars and basses with active pickups, electro-acoustic guitars with built-in preamps, and line-level instruments such as keytars or Roland Aerophones.
Can I use the WL-20L with passive pickups?
Yes, you can use the WL-20L with passive pickups. However, it will not provide the cable tone simulation that the standard WL-20 model offers, which might alter the tone compared to using a cable.
What is the maximum transmission range?
The system offers a transmission distance of up to 15 meters (50 feet) under optimal line-of-sight conditions. This range may vary depending on local environmental factors and obstructions.
Can multiple WL-20L systems be used at the same time?
Yes, up to 14 BOSS wireless systems can be used simultaneously in the same space, provided there is sufficient separation and minimal interference.
Troubleshooting
No sound or intermittent signal
Ensure both the transmitter and receiver are charged. Redock the transmitter and receiver for 10 seconds to re-establish the wireless connection. Check that the transmitter is securely plugged into the instrument and the receiver is securely plugged into the audio chain. Verify that the transmission distance is within the specified 15-meter range and that there are no major obstructions.
Low battery indicator
Charge the transmitter and receiver using a standard USB adapter and the included cable. Docking them together allows for simultaneous charging. A full charge provides up to 12 hours for the transmitter and 10 hours for the receiver.
System not connecting
Ensure both units are within close proximity (docked is best for initial pairing). Clean the charging/connection contacts on both the transmitter and receiver. If issues persist, try charging both units fully and then repeating the docking procedure.
Audio quality issues (hum, buzz, or distortion)
While the WL-20L is designed for clear audio, ensure your instrument's pickups are functioning correctly. Test the system with a different instrument or audio output to isolate the source of the problem. Avoid using the system in environments with heavy wireless traffic or strong radio interference.
Pros and Cons
Pros
- Effortless plug-and-play setup requires no technical expertise.
- Ultra-low latency ensures a responsive playing feel.
- Reliable wireless connection with stable performance.
- Long battery life supports extended playing sessions.
- Compact and portable design.
Cons
- Does not include cable tone simulation, which may be desired by some players with passive pickups.
- Transmission range can be affected by local environmental conditions.
- Only one spare transmitter is available separately; no dual-transmitter kits are standard.
- Requires a separate USB adapter for charging (not included).
Setup, Compatibility & Care
Setup: To initiate the wireless connection, simply plug the transmitter into your instrument and the receiver into your amplifier or pedalboard. Then, dock the transmitter and receiver together for approximately 10 seconds. The units will automatically find and establish the optimal wireless connection.
Compatibility: The WL-20L is ideal for instruments with active pickups, electro-acoustic guitars with built-in preamps, and line-level devices. It can also be used with passive pickups if the absence of cable tone simulation is preferred. The receiver features a standard 1/4-inch (6.35 mm) output jack. The system charges using a standard 5V USB adapter (500 mA or greater) and a micro USB cable (included).
Care: Keep the transmitter and receiver clean by wiping them with a dry or slightly damp cloth. Avoid exposing the units to excessive moisture, dust, or extreme temperatures. Ensure the charging contacts on both units are clean to maintain a reliable charging connection. Store the units in a safe place when not in use to prevent damage.
