BOSS PQ-3B Bass Parametric Equalizer. The item includes the main unit only. *Box, manual, adapter, etc. are not included. Operation has been confirmed. There are some scratches and dirt. It will be shipped via either Takkyubin Compact or Yu-packet Plus. *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 #BOSS #Boss #Equalizer #Equalizer #BOSSPQ3B
