BOSSWL-20L Guitar Wireless System

I play out just about every weekend (I'm a bass player) with a variety of instruments, both passive and active, made in 1983 through 2023. I've used, very successfully, the Fiddlerman FWS-10 for a couple of years without having a backup / replacement wireless system, so after a lot of research I settled in on the Bose WL-20L, primarily because of the 7-hour receiver battery life, the small size of the units, and the fact that EVERYTHING is auto-magic with them, including selecting the best channel available out of 14. I know there are some guitars / devices it won't work properly with because the little button next to the 1/4" jack isn't very long and it's used to turn the unit on and off, but it works with my tuner pedal, my Fender Rumble amps, and all five of my basses. Latency is absolutely negligable, the unit operates quietly, with great tone on both active and passive basses (just a slight tinge of crispness on passive basses). Some people have said that it makes a clicking noise. I can get it to do that too, if I PUT MY PHONE RIGHT NEXT TO THE RECEIVER OR IN MY POCKET ON THE TRANSMITTER SIDE OF MY BODY (don't do that, silly)., as it will interfere with the connection with the transmitter. The other key to having a great experience with this unit is to make sure everyone else has their wireless devices on before you plug your transmitter into your receiver to have it select a channel automagically (takes 10 seconds). You have more channels available to you with your Boss unit than they do with their puny human units, so it makes sense to choose last, and the Bose unit does a great job scanning the environment and getting you a clean channel.This is a fantastic, gig-worthy wireless system which is now my #1. No tone issues. No dropouts. No latency issues. No battery life issues (wish it was replaceable, but oh well). No range issues. It just works and you don't have to worry about it at all. Yes, like a lot of Bose stuff, it's a little pricey, but you get what you pay for. I need a reliable system to use 35-40 times a year playing out with my band, and that's exactly what I got in the Bose WL-20L.

Expectations met.

Super easy to use. Just plug it in and off you go… no cable to get tangled up, trip over, accidentally pull out….Missing: I don’t see any sort of battery level indicator. I didn’t know it needed charging until it just stopped working. Ooops.It would be nice if there was a swivel on the transmitter to keep it closer to the guitar body instead of sticking out so much. Still, works great and easy to use and charge.

Surprised and quite pleased at how well this wireless system functions. Unbeatable range, even around concrete walls in different rooms! No recognized latency, and both volume and tone appear unaffected. Unbeatable value with typical Boss build quality and durability. Highly recommend!!

These do what I need them to do, which is to free me from a cable. I've not had problems with interference--yet--but if I do, there will be little I could do to avoid it. And that's one of three problems with this. First is that you can't change channels in case another wireless instrument interferes. Second is that you can't turn them off other than to remove them from their respective ports. That's a pain because you now have these two small items lying around that you have to plug in again when you're ready to play again. Finally, they charge while plugged into each, which should mean that they charge at the same rate and max out at the same time. Not so, at least not with the pair that I have. Went to practice the other night after having left the two plugged into the charging cable all night and day. Should have been more than enough time to fully charge them. Got to rehearsal, and one was dead, while the other was fully charged. Strangely, it was the unit that has the charging cable port that wasn't charged. So how the one that doesn't charge directly but charges through the other was fully charged while the one plugged directly into the power wasn't is beyond me.I now know better, so charging shouldn't be a problem in the future, and right now the lack of channel options isn't a problem, so I'll keep using them until I don't.

Right out of the box . Worked flawlessly thru a pair of gigs this weekend.

Disappointing…cuts out when I’m only 10 feet away from the transmitter and receiver. I was really hoping it would work for the battery life, but cut outs cancelled any benefits.

Mine has worked every time, including about 15 gigs, with not one drop out. Long charge. No noticeable tone loss.
