I've played Martin since I was a young man. I've owned a couple of D-35's, and a 000-18; I now have a D-76, D-41 (1974), and a Custom shop Dreadnaught (Tree of Life). The only one I have set up to record with is the D-41. Does anyone find issues with the intonation of 1970's Martins? I once played a pre-war (Am Civil War)Martin made in New York and it was still beautiful (though the colors had long since faded), light weight, and sounded fine. Elegantly built.
