Be sure to add me to your favorites list Original, Very Large, ROLAND GR-1 Guitar Synthesizer Owner's / User's Manual Book, made in 1992 in Japan. This is an original owner's manual book for the ROLAND GR-1 guitar synthesizer. It is in overall very good condition, and it's full of information on this unique instrument. I had one of these models years ago and you really need the manual to get the most of it. The covers show some small marks and wear, while the pages are all very good, with many closer to like new shape. It is an original Roland document, printed in Japan, from 1992. This book is very thick, and would be an excellent reference for the GR1 player! 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!
