In the mid-late 1960s, Kanda Shokai also exported some Greco-branded guitars based on Hagström and EKO designs for Avnet/Goya in the USA.

By the mid–late 1970s most Greco Gibson-like models were being made with set necks and open-book Gibson headstock designs.

Starting in 1979, the Greco "Super Real Series," which made available high standard replicas of Gibson and Fender models, was introduced.

Beginning in 1982, the Greco "Mint Collection" continued the high standard of the "Super Real Series."

Some notable guitar players who have used Greco guitars include Ace Frehley, who used Greco Les Paul replicas when his band, Kiss, was on tour in Japan, Millie Rose Lee of Dead Witch, and Elliot Easton of The Cars.

Peter Tork of The Monkees on his 1979–1981 solo tours had two of the Tobacco Sunburst Les Paul models.

Among the electric guitar models that Greco offered during this period, were two thin semi-hollow body style that were equipped with the patented “Shrike” pickups.

The tuners were the same as the Teisco Spectrum 5 of that period, and the neck plate had the L-shaped pickup patent number stamped on it.

[11] 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.

There were also some transitional Greco models from 1981/1982 that have a mixture of "Super Real Series" and "Mint Collection Series" features such as a "Super Real" model with an open O letter in the Greco logo instead of a closed O letter.

The Super Real EGF (flametop) and EG series higher end models featured nitrocellulose lacquer finishes and fret edge binding and some of the Super Real lower end models also featured fret edge binding.

The lowest priced Greco Les Pauls sometimes had different wood combinations from the regular Maple and Mahogany.

The type of pickups varied depending on the guitars original selling price and the Nisshin Onpa (Maxon) made "Dry Z" or Fuji-Gen Gakki made "Dry 82" pickups were reserved for the top end models.

"Mint Collection" models with a K after the numeric price designation (e.g. PC-98K) came with factory-installed Kahler tremolo (vibrato) bridges.

The Cor-Tek-made Greco guitars have square-shaped, brick-like nuts with no slope and also often have shielding paint in the pickup and control cavities.

Other higher priced no-serial Greco Les Paul and SG models were made by Tokai.

The no-serial Greco guitars made by Tokai have square-shaped routing holes at the bottom of the pickup cavities whereas the no-serial Greco guitars made by Cor-Tek (Cort) have thinner rectangle-shaped routing holes at the bottom of the pickup cavities.
