Boss WL-20 Wireless Instrument System (with Cable Tone Simulation)

The Boss WL-20 grants the freedom of a wireless rig with no bulky bodypack! Just plug the transmitter in your guitar, and the receiver into an amp or pedal.

Part of the Boss WL-20 series, the Boss WL-20 guitar/bass wireless system includes "virtual cable" technology with built-in cable tone simulation. If you play a guitar or bass with standard passive pickups (the most common pickup type), the WL-20 model is probably your best choice. It includes built-in cable tone simulation, which reproduces the natural capacitive effect that's introduced when using a 10-foot/3-meter guitar cable with passive pickups. This effect rolls off the treble very slightly, giving you the warm tone you're used to hearing with a normal cable.

I bought this for a traveling option and easy and carefree wireless option. It is easy to charge and comes with a cable to charge either or both the receiver and transmitter if you dock the transmitter in to the receiver. You can charge both independently if you have another USB mini cable. I get a good amount of use and can easily last a whole 4-5 hours. I like that it fits in my case easily and can be charged with a Mobile battery pack while I am at the gig while in my case. Sound is good and the range is great, about 30 feet is all I have really tried it may go more, but that is enough to move around when playing without the hassle of a cable trip or Jack Snap. I am 3-4 Months using it and am very pleased so far CJWII
