The Epiphone 5102T / 5102TE was introduced in 1970 at a turning point in Epiphone history when the company stopped manufacturing in the USA and began importing guitars from overseas. The Epiphone 5102T was made in Japan by Matsumoku and was a thinline ES-335 style hollow bodied electric. Available cherry red finish, it had a bolt-on maple neck, rosewood fingerboard with block inlays, tune-o-matic style rocker bridge (with Teflon covered rollers). vibrato tail-piece (with wood-insert). It had a maple laminate body (almost hollow except for a 3/4" square solid block underneath the bridge), Pickups were two exposed double-coil units (humbuckers?). The 1971 the 5102T model was replaced by the almost identifcal EA-250. The Epiphone 5102T / EA-250 is identical to the Aria 5102T apart from the headstock logo - both were made in the same Matsumoku factory.
