The GSR100EX is a Soundgear series solid body electric bass model introduced by Ibanez for 2008. It has been produced in both Indonesia and China as part of the entry-level GIO line. It replaced the GSR100.

The GSR100EX features a double-cutaway basswood body bolted to a maple neck with a 24-fret rosewood fingerboard with white dot position markers. Components include a single Ibanez PPD4 passive pickup, a B10 bridge with 19mm string spacing, a plastic nut and Ibanez tuning machines.

The body material has changed several times over the years; most recently to poplar. For 2018 the rosewood fingerboard was replaced with jatoba.

The GSR105EX is a similar five-string model. The GSR100EXB is a similar model with black hardware. The GSR100EXM is a similar model with a maple fretboard. The GSR100EXL is a left-handed version.
