Nowadays, there are many makes and models of electric guitars, but back then, in the late 70's, before Greco's Super Real and Tokai came out, there were all kinds of Les Paul and Strat knockoffs...not perfect, but hey, it was the heyday!
Greco, Fernandez, Aria... there were several manufacturers, but there was a TV show called "Rock Omoshiroku" hosted by Haruo Chikada at the time. The show was sponsored by Greco, and in one of the commercials, Akira Wada of Prism played very fast and looked really cool.
I had a strong impression of that. And then I had to decide what to buy, and I could only think of the Les Paul that Jimmy Page uses.
I remember now, there were two factions around me at that time, Zeppelin and Purple. Of course, I was a Zeppelin guy...so when it came to electric guitars, it was Les Paul or Strat. One day, I saw a Greco EG-600J (dark green!?) Jeff Beck model Les Paul at a music shop in Shinjuku. I got a catalog that day and went home, but I had a good time staring at the catalog for a while.
