This is a Roland TR-6S Rhythm Performer. I purchased and used it, and there were no issues with its performance. I bought it new from Rakuten Ishibashi Gakki about two years ago, but I haven't used it much because I don't make rhythm-based music often. It has only been used indoors, so it's in beautiful condition with no noticeable scratches or stains. Of course, there are no problems with the sound or functions. It has been updated to ver. 2.0, which allows you to use the incredibly realistic CR-78. All accessories, including manuals and other documents, are included. The original box and packing materials are also included. I will ship it in its original box wrapped in bubble wrap and then placed in a cardboard box.
