Boss WL-20L Product Overview by GAK

plug and play wireless system for Guitar and Bass, the WL-20L makes going wireless extremely simple. The system features Boss' lighting fast technology, making latency almost non-existent.

Previously many people have been put off the idea of using wireless systems due to the complicated setup, however, the WL-20L's easy setup makes wireless playing simple and with no cables getting in the way, you're able to move around the stage freely. The system also features cable tone simulation, reproducing the natural effect of a 10-foot/3-meter guitar cable.

The WL-20L features built-in rechargeable batteries, providing you with up to 12 hours of continuous playing time.

Lest we forget that during sound check you can now listen to your tone out front and hear what the audience will be hearing.

    First class product charges both by plugging the other one in and using just one socket instead of having to use both. Lasts for ages, I've had mine for a week now still not charged up yet and I been practicing each day, very reliable signal and works nicely along with my wireless mic system with zero interference. Definitely gig worthy.
