It's worth it


The boss WL-20 system is very impressive. I could walk around my apartment and still have a strong signal! I can't wait to use it live; it also makes it easier to not have to deal with cables getting tangled up if I'm sitting at my studio. It over all makes playing guitar more comfortable.



Wireless system


A must-have for those who play bass and guitar





These Systems are absolutely amazing, they work very well, I could be upstairs with my amp downstairs and it will continue to work, if anyone needs a wireless unit these are the go to



I will buy this product again and again


The Boss wireless Guitar /Bass system gives me so much freedom to move around on stage and ups my end game with positive result with the crowd Thank you Sam Ash for recommend the wireless system its a game changer





A little with the instructions, had to return to the store for assistance from your staff. Very helpful. Thanks



I would buy again


Awesome product! No more cords my husband loves it



Free yourself from guitar cables


What a relief to be liberated from guitar cords to trip over or get tangled! Cordless is definitely the way to go. The sound is true, and while I haven't yet tested the full range of the device, it's perfectly fine if you want to wander a ways from your amp. Just make sure it's charged (and maybe bring a cord just in case...).



Going to buy another set


Love it Small simple works great



Like others Boss products, it rules!


Execelente cost benefit. Robust and reliable product, just like all Boss products. It works perfectly without interference or squeaking and the battery lasts for several hours.



I like it!


So far have only tested the WL-20 Wireless at home; will use it live in a two weeks time. It actually seems to produce a slightly higher volume than playing with my cord, and the tone is the same. The reason of course may be that it is an old cord used for practice, and may well be past its prime. Connects well with the amp when I am a couple rooms away. Very easy to use. Because the transmitter does not fold like some other brands I have noticed advertised, I cannot sit for example on a bed or a couch with my tele because the socket in this guitar points down, though this will not be a problem with many other style guitars. I did purchase the unit for stage use though, and I am pleased with it!
