I inherited a beautiful walnut Technics sx-GN7 with all books and instructions included. I do read music, but I am at a complete loss figuring out all the things this organ can do! It is so over my head. My aunt paid $18,000. for this in the 80's, and would sell it, but would prefer to learn to play it. Any help? Any clue how much it might be worth (for insurance purposes)?
