The best thing since sliced bread. No more tangled up cable, or tripping over it. I like the nice clean sound. I wonder why I didn't get it sooner.



Wireless that doesn't suck


Good product, does what it is supposed to do



I highly recommend the WL-20L Wireless Guitar system!


Overall it's a great product and I'm very satisfied with the tone and overall sound my guitars continue to produce using this great wireless product. I'm also running it through a boss multieffects processor and they seem to work great



WL-20L review


So far so good. Easy to use. Great response.



This is his fourth wireless system like this one


My husband really loves them



This is my second one purchased.


This is great for use with my guitars or bass guitar. Easy to charge up and use. Love It!!





One of the best purchases I have made in a very long time. So easy to use and works beautifully, no latency, no noise, just crystal clear sound and NO MORE CABLES!!! Really like the long battery life/per charge as well. There are cheaper out there but you are going to get what you pay for. I would recommend this product to anyone interested in cleaning up their mess of cables, you won't be sorry.
