How are these old Harmony acoustics from the 60s? I've found a couple of nice examples, gone through and ready to play. There's a H1203, an H162, and an H3221. All about $500 buckaroos. They look cool, have Spruce tops, Mahogany back/sides, appear to be all like OM size. I like "cheap" acoustics, some have that Lightnin' Hopkins tone which I love. Can anybody comment about these models, or Harmony acoustics in general?
