Be sure to add me to your favorites list Original KORG Service Manual for the CONCERT XC-1000, XC-2000, and XC-3000IF Digital Pianos, Original Service Manual / Schematics / Diagrams Booklet from 1996, Printed in Japan. This is an original Korg service manual for the Korg CONCERT XC-1000, CONCERT XC-2000, and CONCERT XC-3000IF models of digital piano keyboards. It is complete, and in useble condition. There are numerous stains on it, but mostly on the covers, with a few on some pages, but many pages have minimal marks on them and nothing keeps the information from being seen and used. This would be extremely helpful if you need to work on / repair / modify one of these large digital keyboards. Original Korg document, printed in Japan, from 1996. 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!
