Custom Audio Japan's Twin Tremolo. The product includes the main unit and manual. *Box, adapter, etc. are not included. Operation has been confirmed. There are some scratches and dirt (good condition). It will be shipped via Yu-Packet Plus or Yu-Pack. *The shipping company may change depending on the situation, but the shipping cost and anonymous shipping will remain the same. I will not answer questions about the serial number other than the part shown in the image. #Effecter #CustomAudioJapan #CustomAudioJapan #Tremolo #Tremolo #CAJTT
