Hello. Newbie here. I am the original owner of a 1980 D25 sunburst. Its been my only acoustic for 42 years. I was looking for that deep even tone. Played it for ten minutes and out the door we go. Never looked back. I have since had some frets replaced and some other work done. Almost like new today with that aged and played richness. I read that it came with a nitro finish. Am I correct in assuming this. I am also looking for a second Guild. Thanks for any input on the subject.
