【Caution】
This product uses the volume pot mounted on the circuit as the master volume.
Please use a precision screwdriver matching the trimmer pot. Also, trimmer pots are very delicate, so please be careful with handling.
Please use 006P (9V) for the booster battery. Also, if you leave the plug inserted, the battery will be depleted, so unplug it when not needed.
Sometimes it is necessary to remodel the instrument itself. In that case please consult your dealer or a local repair shop for installation.
Designed according to the characteristics of the passive pickup, if you connect an active pickup, the DIP switch on the main unit will not function. Only the gain control works.

Please feel free to contact me if you have any questions.
