D-25s
In his post, John Kidder said, "...They both had some sort of undefinable soul that just made them excellent guitars."
I've owned close to 2 dozen Guild D-25s over the last 30 years. Currently, I only have my 1975 G37SB (extremely similar to the D-25) - but just like John says, it is one of those guitars with "some sort of undefinable soul". It is an exceptional guitar and is the quintessential reason I only play Guilds - they speak to me. NO, they SING to me.
I know today where several of the D25s are that I have owned and sold - their owners are exceptionally pleased with them and vow never to sell them. I've never had a D25 with a flat back, but have played several. I believe the arched back was an amazing improvement for warmth, balance and projection. For the money, it makes the D25 a terribly terrific bargain. Everytime I see one float by on Ebay, I wish I had a littel extra cash....CHeers! dbsmith
