The WL-60 from BOSS is a wireless system for electric guitarists and bassists. Its form factor consists of a bodypack transmitter that clips to your belt and is where you plug your instrument. The receiver is the size of a small stompbox and sits on your pedalboard. You can plug the receiver into the first pedal of your chain. The system automatically scans 14 channels for the strongest signal, and you're good to go. Now you can walk across the stage and not worry about dragging all your gear behind you. Latency is as low as 2.3 ms, and the system gives you a 20 Hz to 20 kHz frequency response to ensure none of your tone is lost in the wireless world. The transmitter and receiver both accept battery power, though the receiver also sports an input for a separately available AC adapter. Should you power the receiver from an adapter, you can daisy-chain power to another pedal from the DC output.
