First post, happy to be a part of the community! I've had the "bad" luck of really falling in love with my friend's 1965 D-40 and am trying to get a similar guitar for myself. Right now I'm considering a 1970 D-40 online and wanted to see if anyone here had experience in playing a wide range of Hoboken era acoustics to get insight on how much they vary instrument to instrument and year to year. I know it's a risk to buy online without the opportunity to actually get my hands on it but I also could see there not being a huge amount of difference between the guitars (aside from the obvious fact that they may have lived different lives over the past 50 years). Anyone got any insight? My principal questions are: a) would the necks be the same measurements; and b) how much tonal variation could I expect between the two? Thanks in advance!
