* The basic functions of the WL-20L are the same as those of the WL-20, but cable tone simulation is not installed. Therefore, it is optimized for instruments where the cable has little effect on sound quality, such as electric acoustic guitars with built-in preamps, guitars and basses with active pickups (pickups that require batteries), and even instruments with line-level output such as shoulder keyboards and Roland's Aerophone. In addition, the WL-20L can be used with passive pickups if the sound quality changes typical of cables are not required.
*Not compatible with the following guitars.
● Specifications are limited for the following types of devices.
-Devices with a stereo standard type (TRS standard type) OUTPUT terminal
*Only the signal from the L side (Tip side) is output.
● Not compatible with the following types of guitars.
・Guitars that do not have enough space (cylindrical space with a diameter of 18.5 mm and a depth of 5 mm) to attach the transmitter to the mounting jack
・Guitars with special electrical wiring specifications
- Some guitars with active pickups (※1)
- YAMAHA Silent Guitars (※2)
(※1) In the active circuit of a guitar, the general wiring method for the TRS jack output is Tip = audio, Sleeve = ground, and Ring is for battery ground. In rare cases, there are guitars where the Ring and Sleeve are wired in reverse, in which case the active circuit of the guitar will not work properly.
(※2) It will not work due to electrical wiring specifications.
*There are some models of guitars/basses with active pickups that cannot be used.
