Gibson's top of the line thinline semi-hollow series, this ES-355 stereo from 1978 is a great example of the design! Though they were discontinued in 1982 due to lack of demand and they're functionally very much in line with the 335s and 345s, there are a couple notable differences, including an ebony fretboard (no Brazilian rosewood to worry about), gold hardware, and MOP block inlays.
This one is in very good condition for its age, with the natural wear that comes with a well-played life. The pickups have been rewound, there are replaced wires in harness, and the replaced pickguard is stowed in the original hardshell case.
