This is an Alesis electronic drum set. I purchased it new from Shimamura Music for 37,800 yen, but I hardly used it and have been storing it assembled at home. I've played it a total of about 5-10 minutes, less than 10 times. I tested it before listing it, and its operation has been confirmed. The items in the images are all that are included. The film on the control panel has not been peeled off. I will disassemble it for shipping. I will pack it in a way that makes the structure as easy to understand as possible, so please assemble it yourself. * As shown in the 5th image, the cables originally have tags with the names of the devices they connect to. Please also refer to reference videos online, etc.
