Context and Positioning
The WL-20L is part of the BOSS WL-20 wireless range, designed to offer the freedom of wireless without the complications of traditional systems. Its "all-in-one" approach prioritizes simplicity, with a rechargeable transmitter/receiver duo, ready to play within seconds.
Who This Wireless System Is For
The WL-20L is the best choice if cable capacitance has little (or no) influence on your sound: electro-acoustic guitars with preamps, guitars or basses with active pickups, and instruments with line outputs (keytars, digital wind instruments, etc.). It also works with passive pickups if you do not seek the slight high-frequency attenuation that cable simulation provides on other models.
