Listing is for a Roland System 1 plug out synth. It has the original box, power adapter, manual, and a usb-midi interface. The box is slightly dusty and a bit scuffed on the corners, however the synth is in absolutely immaculate condition, and has had at most 5 hours of use in total. Please note that the power adapter IS AN EU PLUG! I have tested it and everything seems to be working. Do not hesitate to message me if you have any queries, and have a nice day!
