I had acquired over the weekend a 1981 Alvarez DY-75 Acoustic guitar and it is just a wonderful guitar. I had done a google search and came up with very little information, but to be expected. I pieced some information but nothing specific to this year and model. What I am mostly curious about is whether or not the back and sides are lamenated during this time period as I do know that the later 80's models do have laminated rosewood back and sides. It is hand signed as well and is really a unique guitar. Thanks for any info!
