Be sure to add me to your favorites list Original Yamaha MR10 Drum Machine Original Vintage Owner's Manual Book, Japan, 1982. This is an original Yamaha User's / Owner's / Operating Manual for the Yamaha MR 10 drum machine unit, part of the Producer Series of the early 1980's. It's in good to very good condition, with some marks on the covers and finger indentations on some pages, and it's complete and very helpful if you have one of these now classic drum machines. It's all in English and is an original Yamaha document from Japan, with great information on using, playing and caring for your Yamaha MR10! This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thank you for looking! Check out my Store!
