My first guitar was a Harmony Soveriegn which I bought from the Sears catalog. Sometime in the late 60's I was climbing Mt Lemon near Tucson with the Harmony on my back (no case) and crushed it on a granite boulder. Then I got an Ovation Troubadour with the round fiberglass back and played it for a long while. I bought a Martin J-40 in the early 90's and a second Martin two years ago. (I don't take the Martins rock climbing).
