This is a Guyatone PS-011 DISTORTION SUSTAINER. The item includes only the main unit. *Box, manual, adapter, etc. are not included. Operation has been confirmed. MADE IN JAPAN. There are some scratches and dirt (relatively good condition). It will be shipped via 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 serial numbers other than those shown in the images. ↓ I am also selling other Guyatone effects pedals. ・PS-103 Guyatone Compressor Guyatone Old Model #GYTPS103 #EffectPedal #Guyatone #Guyatone #Distortion #Distortion #MadeInJapan #GTNPS011
