Be sure to add me to your favorites list Original Roland JD-800 Synthesizer Keyboard Reference Manual Book (Owner's Manual II), 1991, Made in Japan. This is a hard to find, very good condition original Reference manual book for the Roland JD-800 synthesizer keyboard. This is the very thick Reference Owner's Manual number II / advanced manual, for this 1991 synth. This book is an absolute must-have for this very advanced synthesizer. It shows some wear and marks on the covers, with some creasing on one side of some of the pages where it got damp once, but overall the pages are in very good condition. This large book is complete and goes into details with playing and programming your JD-800. This is an original Roland document, and was printed in Japan in 1991. I have 2 of them available at this time, both with similar wear on them. This is what you want if you have a JD. This is a powerful synth and you need the advanced manual to get the most out of using it! 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. Thanks for looking! Check out my Store!
