I realize this is an old post, however, that being said, I just found and bought a Godin Grand Concert Duet Ambiance that I found for sale online yesterday. It will be here next week. I just wanted to add that Godin does have the one page sheet on their site for this guitar and wanted to provide the URL for others that might search for a manual and find this thread.

I certainly hope I enjoy mine as much as you all do!
EDIT: Sorry, I misread the OP it clearly states NOT the Ambiance, my bad. Moderators please remove this post.
