This is a 1978 Gibson J-50DX. It's a square-shouldered Gibson with XX bracing. It has scratches and dents. String height at the 12th fret: 6th string...approx. 3.0mm, 1st string...approx. 2.5mm. Nut width is about 43mm, scale length is 643mm. The saddle is made of mahogany. Although 1970s Gibsons are often said not to resonate well, this one, with 47 years of age, produces the unique, crisp Gibson sound of this era even with a light strum. While the 1978 instruments, with their hard tone, had a strong personality and weren't commercially successful, they can be considered valuable models. There are dents, scratches, yellowing of the binding, and some minor cracks, but it's in good condition considering its age. *The hard case is the original case, although the logo has faded. *There are no cracks in the wood, bridge separation, or bracing separation.
