This was the time when US-built cars were 2-ton behemoths and the Japanese dared to export the little Toyotas..eventually ran quality-control rings around the Detroit-built iron.The only GX guitar I know of from Yamaha is the GX-1 which is a headless electric model and therefore not what you have.I'm not aware of any othe I think the model is "FX 3000".If your serial number has 2 lines of numbers please enter only the bottom row to the lookup form below.
