I have a DR-7 that I fished out of the closet. I learned chords on it in 1972, when my dad bought it for me when I was in high school. Does anyone have the specs for that model or can tell me where to get them? It appears to be Rosewood B&S and Spruce top. It is beat up but in solid shape (some finish checks on top and plenty of dings). The nut is cracked and can be replaced and the frets need dressing and or replacement. I am considering removing the bridge plate with the adjustable angle bridge holder, with a standard Marting style bridge. The tuners need to have several mounting holes filled and tapped as they are stripped. I may replace with better tuners. Any opinions on whether the investment to fix it up would be worth it?
