1983 Martin D12-18 Twelve String Guitar, Serial #438798. Mahogany back, sides and neck. Spruce top. Very nice condition, a few nicks and scratches. There is a four inch crack on the back. There is a small patch of buckle rash. I've owned this one for two years. I have a Gibson LG12 twelve string, which i prefer. The frets are 95% and I don't think this guitar saw a lot of use. UPDATE: I'VE GIVEN THIS MARTIN TO MY GUITAR GUY FOR CRACK REPAIR, ASSESSMENT AND REPORT. I EXPECT THIS WILL TAKE A COUPLE MONTHS. THE PRICE WILL BE ADJUSTED DEPENDING ON THE EXTENT OF THE WORK DONE. CHEERS, JERRY Includes the original Martin hard case. If your player needs a nice Xmas present, here it is! $1,850.00 o.b.o.
