This Carter 12-string is listed on Reverb.com by a friend of mine. I got to try the guitar this morning, and as far as I can tell, everything seems in order. I don't play Universal so the setup really threw me off (E's on the right-side levers!!!) but I think everything is the way it should be. The guitar is light (44 lbs in the case) and plays easily. Pictures of the undercarriage and changer are included in the listing, so please let me know if something doesn't look right. The guitar was originally sold by Al Brisco of Steel Guitars Canada.
Again, I am NOT the seller, so anyone interested should follow the Reverb link. I will make sure a donation is given to the Forum if it sells to a member who saw this post. Seller is asking for 2,000$, which seems like a pretty good deal to me.
