Im not sure if this is, a Samick? A Cort GE20 perhalps? TRC is the same as Cortez and 3 holes shows it may be MIJ. Its a bolt on neck. Sounds awesome! And any idea what they go for?
More than likely Korean Cort. they were still into the sunburst plywood (from the rare Asian laminate tree) paul copies into the early 80's. Price..... 125-200 maybe.
Some of my guitars: 64 or so Domino Beatle bass; 73 Ibanez 2398; 79 Epiphone Genesis; 79 Manoman; 78 Gibson L6S; 95 Ibanez JS-700; 04 Samick Lasalle JZ3: 05 Ibanez AS73; 06 Gibson SG Faded, 07 Gary Kramer Simulator T and quite a few others.
