 By the mid/late 1970s most Greco Gibson-like models were being made with set necks and open book Gibson headstock designs.Some other Greco Gibson-like models from the 1970s had a different headstock design, more like a Guild headstock design, that had a Greco logo with equally sized letters.Starting in 1979, the Greco "Super Real Series" was introduced which made available high standard replicas of Gibson and Fender models.
