My second guitar (which currently lives ta my parents' house, but will have ot be sold soon) is a similar construction, though mine is by Tangelwood, no cutaway, regular soundhole. There were quite a few companies doing these in the late eighties to early mid-90s when Ovations were considered to be all the rage, especially before solid-body "regular" acoustics started to pop up at affordable prices. This one very much looks late eighties/early 90s to me, both by design and there's a certain.... sheen to the look that doesn't 'ring true' to me were it 60s. To be frank, it also looks - and from your description plays and sounds - too good to be a 60s budget model. I tend to find these guitars are great for a nice, bright acoustic sound, edging closer to but still more "organic" than, the sound of a clean electric Strat or Tele neck sound, say. Some of the purists would sneer at the fibreglass body, but with an open mind they can be very nice indeed.
