For guitarists and bassists with conventional passive pickups (the most common pickup type), the WL-20 model is the perfect choice. The receiver has an integrated cable simulation that reproduces the natural capacitive effect of a 3m guitar cable in conjunction with passive pickups. This effect slightly attenuates the highs and gives you the warm sound of a wired instrument. After the powerful BOSS wireless technology was first used in the Katana-Air wireless guitar amplifier, the WL-20 series now also benefits from the outstanding sound quality and wide dynamic range. The wireless systems operate in the 2.4 GHz frequency band and automatically find the optimal channel to ensure maximum stable audio transmission without drop-outs. What's more, thanks to the extremely low latency of just 2.3 ms, you won't hear any time lag when playing. Up to 14 BOSS wireless systems can be used simultaneously in one room. This way, multiple musicians can benefit from wireless freedom at the same time. The WL-20 wireless system is as easy to use as a conventional guitar cable. The compact transmitter plugs into the instrument's input jack, while the matching receiver connects to a pedal or amplifier. That's it!
