This vintage Gold Star is a GF-100 which features the mahogany neck and resonator. This one has the hearts and flowers inlay along with a resonator in the GF-85 configuration. The era from 1978 until 1984 is the most sought after being the “first generation” made in Japan. This one shows a little patina, but still in fantastic condition. If you have any questions or desire, additional pictures, don’t hesitate to ask. Thanks for looking.
