## Description

From the manufacturer About BOSS BOSS, a division of Roland Corporation, has achieved legendary status among guitarists, bassists, and vocalists with a diverse, class-leading product line-up of creative tools with exceptional sound, intuitive control, and rugged durability. Since 1977, BOSS has lead the way with innovative effects pedals, amplifiers, multi-effects processors, and loopers to wireless systems, vocal effects, tuners, metronomes, rhythm machines, recorders, and more. WL-20 Wireless System Wireless freedom made easy for your guitar, bass and other electronic instruments! Have you always dreamed about going wireless with your instrument, but were put off by the complicated setup, tone loss, and bulky adds-ons? If so, the WL-20 series is for you! Driven by new lightning-fast BOSS tech, these ultra-compact music tools deliver premium sound and plug-and-play operation that completely eliminates all the hassles normally associated with wireless systems. Lightning-fast BOSS technology. No compromise to the tone or feel of your instrument. Plug-and-play operation that eliminates all the hassles normally associated with wireless systems. With no worries about cable management, move about freely while playing at home, with friends and performing on stage. Lightning-Fast BOSS Wireless Technology Equipped with high-performance BOSS wireless technology that debuted in the Katana-Air wireless guitar amp, the WL-20 series delivers exceptional sound quality with wide dynamic range. Working in the 2.4 GHz frequency band, the optimum channel is set automatically to ensure rock-solid audio performance with absolutely no drop-outs. And with ultra-low latency of just 2.3 ms, you’ll always enjoy great playing feel with no lag whatsoever. Up to 14 BOSS wireless systems can be used simultaneously in one space, allowing multiple musicians to enjoy wireless freedom at the same time.* *Environmental conditions may affect the actual number of simultaneous systems available. Plug In and Rock with Automatic Wireless Setup A WL-20 system is literally as simple to use as a standard guitar cable. The small transmitter plugs into your instrument, while a matching receiver plugs into a pedal or amp. That’s it! With the WL-20 series, there’s no fiddly channel setup required. Just dock the transmitter and receiver together for about 10 seconds to automatically set the optimum connection. Easy Charging via USB When docked, the built-in batteries in the transmitter and receiver can be charged together with a standard USB adaptor (5 V/500 mA or higher), the same type used with the latest smartphones and tablets. The transmitter and receiver can also be charged separately, and a micro USB cable is included for charging. Built-in rechargeable batteries provide up to 12 hours of continuous playing time* * A full charge provides 12 hours of time for the transmitter and 7 hours for the receiver. WL-20: Built-In Cable Tone Simulation If you play a guitar or bass with standard passive pickups (the most common pickup type), the WL-20 model is probably your best choice. It includes built-in cable tone simulation, which reproduces the natural capacitive effect that’s introduced when using a 10-foot/3-meter guitar cable with passive pickups. This effect rolls off the treble very slightly, giving you the warm tone you’re used to hearing with a normal cable. If you do not require cable tone simulation, the WL-20L does not provide this feature.

Review: Good product. For those trying to decide whether to get this 'L' version or the other read on... - Well made and works great. No noise. Some smart design features: it has no switches and it switches on when plugged in. Pairing is achieved just by plugging one unit into the other and they can be charged in this way too, meaning they require only one lead. All good ideas. Compared to a lot of the cheaper units, the battery is clearly physically bigger (and probably of higher quality) which will be why Boss can claim 10 hours of operating time. I tried two cheaper makes before buying this: The Lekato WS-70 and the Getaria one: The WS-70 has rave reviews everywhere but it did horrible things to my sound despite otherwise working well - it squashes out all the attack and is dull. The Getaria is great for its cheap price but it's a little noisy when used with distortion and the construction is somewhat flimsy compared to the Boss. I agonised over whether to buy this version or the version which simulates the treble roll-off caused by the capacitance of a lead. Even Boss' own sites contradict themselves a bit, with one saying the 'L' stands for low impedance and the other saying the only difference is the treble cut. After watching a Youtube video of a guy comparing the other one to a good lead, it seemed more like it was simulating a curly lead from the 1970s. The treble roll of was too much so I opted for this one - which they recommend as being for active guitars and synths etc. My own comparisons found this to be very similar to using a good quality lead so I don't really see the point of the other one. Why they didn't just make one model and put a switch on it for that I don't know. Also, on this 'L' version, the transmitter is a different colour to the receiver which seems like a useful and obvious thing to do, whilst on the other version they are the same. Unless you think that a fairly substantial treble cut would be a good thing for you I would buy this one. UPDATE Have now done four or five gigs with the system and it's been flawless. Worth the extra money over the cheaper systems.
Review: Great bit of kit. - I get fed up tripping over cables. This is easy to set up and I have found no difference in sound quality. I found two boss models on desertcart and I picked this because its easier to charge up (Plug transmitter into receiver, attach mains and it charges up). Plenty of time to play before recharging. It easily gets you through the night. I used it for rehearsals for 6 hours before recharging and it still had juice in it. The main light changes colour when it needs charged and that hasn't happened yet. However the main test is freedom of movement and I cant fault it yet. I moved around whilst playing and found no difference in sound quality. Also, all pedals work fine. Its placed at the start of your pedal board with all effects added after it. There is also an input socket as well as an output to next pedal (or amp). This then means that if you see the low charge light come on and don't want to take a chance, you can then plug in a normal cable between guitar and the receiver. This then overrides the receiver and you can play as you would normally. Excellent bit of kit.

## Questions & Answers

**Q: Will this work with a keyboard/synthesizer?**
A: Hello and thank you for your question about our products.
Use with a synthesizer is possible with our WL-20L product.
Note, however, that with tones that have strong dynamics, such as square wave, piano, and xylophone tones, the sound is distorted depending on the keyboard range, and so raising the volume level is not possible.
Use the instrument with the volume adjusted to a level where no sound distortion occurs.
Connect the transmitter to the synthesizer's OUTPUT jack.
To determine whether connecting the transmitter and receiver to the equipment you're using is possible, download and check the WL-T (Transmitter) Outline and WL-20/WL-20L (Receiver) Outline available via our official website.
If you want to use stereo sound, check whether simultaneous connection of two sets is possible.
Regards,

**Q: Do these work well with active pickups?**
A: Yes these work great a bit expensive but you only get what you pay for, ive used these on active and none active pickups and no problems A1  *****

**Q: Can I plug the receiver into headphone?**
A: No it would be like plugging headphones straight in to a guitar, there would be no sound as the signal needs to be amplified

**Q: Can you have 2 guitars in band on different channels using 2 systems**
A: Hi,

That is fine as long as you are linked on different channels.

Regards
