BOSS Wl-20L Compact Wireless Instrument System, Plug-And-Play Wireless Systems for Guitar, Bass, And Other Electronic Instruments

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.UPDATEHave now done four or five gigs with the system and it's been flawless. Worth the extra money over the cheaper systems.

Very easy to set up, long time to charge (6hrs) but last for at least 3 or 4 hours live playing or practice. Maybe more if you need it.Boss quality built, and fit several different guitars 🎸

This is a robust and compact wireless cable replacement. extremely well made and works well over long distances (10m through solid walls). Works perfectly with passive pick-ups on my Gretsch, Ibanez and Yamaha guitars. The WL-20 version (supposedly for passive pick-ups) made a fairly loud buzzing noise through the amp so I exchanged it for this which solved the problem. Oh, and it might knock out your WIFI while you’re using it too- so be warned!

Bought this as i have a schecter silver mountain with a sustaniac pickup, i get an annoying ticking sound whether i plug into the boss gt100 or straight into amp when using the schecter, so no use for that guitar.other guitars with passive pickups it is flawless, easy set up and linking, should have just bought the WL20 and saved a few £s, schecter works no problem with the Boss WL60did contact Roland/Boss and they suggested using a short extension cable between the guitar and WL20L which i dont see the point in doing

Very handy bit of kit to have for live gigs, saves all the heartache of restricted manoeuvrability that comes with a lead, not to mention removing trip hazards. The sound quality has been perfect for me, and I haven’t experienced any signal interference. I would suggest first time users read the instructions carefully. You should twin the paired devices only after you have fully set up your stage and all the other instruments or tech you are using. The device will scan the venue for all other signals, and jump on a frequency that doesn’t clash with what’s already pinging around the space.My only wish is that the battery lasted longer. For longer sets you will need to disconnect it from your instrument and plug it in to charge at a convenient moment.

I have used the Boss WL-20L in live situations on acoustic guitar and bass and in rehearsals on Keyboard and violin. In all situations they have worked really well with no noticeable latency in playing and they have not dropped out.I am really pleased with the Boss WL-20L

The system was OK for all of my conventional uses - various high-end electric and acoustic guitars with Fender twin and Roland JC40 amps - however, I bought it for use with my Godin Encore nylon and Roland AC60 and it couldn't handle it - very loud interference, no matter what I tried. Needless to say, the system was returned for a refund.

You do need to be patient when doing first charge, it takes a while. After that recharging is pretty quick.I have used it continuously for a 4 hour session and it lasted just fine; I have no reason to doubt their claimed battery charge life.I chose this version as I wanted to use with both electric and acoustic guitars.(I already have a wl50 on my pedalboard - so knew the technology worked).
