This is a YAMAHA analog mixer, model MG06. The unit itself is included, but there are no other accessories. The power adapter is missing, so I haven't been able to confirm its operation, and it's being sold as junk. I didn't notice any issues within the range I could assess by touch, such as buttons sticking or knobs spinning freely. However, since it's junk, I cannot offer any guarantees. "Junk" means "scrap" or "defective," and this transaction is for a product that is initially defective. Please do not purchase this item assuming it might be in working condition. This product is intended for those who can handle any issues themselves, such as for parts or repair. Although I don't think it's particularly noticeable, there are scratches and dirt, so please check the photos carefully and purchase only if you are satisfied. I will wrap it in vinyl, use newspaper as cushioning, and ship it in a cardboard box via Yu-Pack (Japan Post) using Yu-Yu Mercari delivery. I cannot change the packing or shipping method, so please purchase only if you understand and agree to this.
