The Fuji-Gen Gakki guitar factory were the main maker of the Greco guitars in the 1970s and 1980s. Fuji-Gen Gakki obtained a CNC router in mid-1981 for making guitar parts and also began to manufacture their own pickups starting in late 1981. The Fuji-Gen Gakki CNC router and Fuji-Gen Gakki made pickups were used for the "Super Real" and "Mint Collection" series starting from 1981 to the early 1990s. Up until 1981/1982, Nisshin Onpa (Maxon) made pickups were used in the Greco guitars including the "Super Real Series" and the guitars were made in a more luthier style with no CNC machines used. The Cor-Tek and Tokai guitar factories were also used to make some Greco models due to FujiGen not being able to make some lower priced Grecos in the late 1980s.
