This is a BOSS SP-505 sampler. It shows signs of wear and tear, such as scratches, due to age, but it functions without issue. I used it without any problems a short while ago, but I am not a professional, so I haven't confirmed everything perfectly. Please understand this before purchasing. The items included are the main unit, power cord, and memory cards (64MB x 2). You can find the manual online. The power cord is not the original, but it works without any problems. Cancellations after purchase are not accepted.
