This is a Guyatone PS-025 TOUCH OVERDRIVE. *It is advertised to have distortion that responds to the strength of your playing touch. The item includes only the main unit. *Box, manual, adapter, etc. are not included. Regarding operation, there are no problems with ON/OFF and distortion, but I couldn't clearly hear the change in sound when operating RELEASE. *Therefore, there is a possibility of "partial failure," so please consider this only if you understand this beforehand. MADE IN JAPAN. There are some scratches and dirt. 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 the serial number other than the part shown in the image. ↓ I am also selling other Guyatone effects pedals. ・PS-025 Guyatone Touch Overdrive Guyatone #GTNPS025 ・PS-103 Guyatone Compressor Guyatone Old Model #GYTPS103 #EffectsPedal #Guyatone #Guyatone #OverDrive #Overdrive #GYTPS025
