Hi Phil- read the forum all the time and respond when appropriate. My first guild was a D-44M back in 1973-520 bucks including case. It was a great guitar; flat-backed and a little fancier than the G-37. The arched back on the 37 makes it a little more open sounding than the 44; IMHO the D-44 a little more resonsant. Mine had the mahogony finish. It was the first really good guitar I ever owned and at the time was going to get a Martin D-18. The D-44m blew the D-18's I played away and it was more affordable. I wish I still had it and everytime one shows up on ebay I am very tempted. F-412's and JF30's are great to and both have that open arched-back tone. Hope this helps.
