* 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.

 (* 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.
