* The basic functions of the WL-20L are the same as those of the WL-20, but without a cable tone simulation. For this reason, electric acoustic guitars with built-in preamps, guitars and basses with active type pickups (pickups that require batteries), and line-level outputs like shoulder keyboards and Roland aerophones Optimized for instruments such as musical instruments that have almost no effect on sound quality due to cables. In addition, even if the pickup is a passive type, you can use the WL-20L if there is no need to change the sound quality specific to the cable.

* The following guitars are not supported.

● The specifications of the following types of equipment are limited.
・Equipment whose OUTPUT terminal is a stereo standard type (TRS standard type)
* Only the L (Tip) signal is output.

● The following types of guitars are not supported.
・A guitar that does not have enough space (18.5mm diameter, 5mm depth cylindrical space) for mounting the transmitter in the mounting jack
・Guitar with special electrical wiring specifications
・Some guitars with active pickups (* 1)
・YAMAHA Silent Guitar (* 2)

(* 1) In the active circuit of the guitar, the general TRS jack output wiring method is Tip = audio, Sleeve = ground, and Ring is for battery ground. In some rare cases, the ring and sleeve are wired in reverse, in which case the active circuit of the guitar will not work properly.

(* 2) Does not operate due to electrical wiring specifications.
* Some guitars / basses with active pickups cannot be used.
