Check out this 1937 D-18 just in stock! It is an absolute killer and one of the top three best sounding D-18s we have ever had. Two Nashville pros played it over the weekend and were blown away. A+ crack free Adirondack top over hand scalloped forward shifted X braces. Original finish. 1 3/4 nut. It plays extremely easily. Notes leap out of this instrument and the sustain is jaw dropping. The pre war D-18 is in my opinion the pinnacle of what Martin contributed to the guitar world. Original open back tuners.
