Hey ZaKaTaK,
Your Hondo 330A is listed in the Price List of the 1977 Hondo catalog posted in the Electric Guitar catalog section of the Catalog Library. Based on price, it was their top of the line Classic guitar that year. Interestingly, the 330A is not pictured or described in the catalog itself. This suggests it was either a new model in 1977 or perhaps a discontinued model. In either case, at least now you know it is a late 1970's instrument.
Keep trolling those swap-meets
