The GSR180 features a double-cutaway nato body bolted to a maple neck with a black headstock and a 22-fret rosewood fingerboard with white dot position markers and white side dots. Components include a pair of Ibanez passive jazz pickups, a B10 bridge with 19mm string spacing, a plastic nut, and Ibanez tuning machines. The hardware is chrome.
