The RG198QM features a basswood (later agathis) body with a bound quilted maple top bolted to a maple neck with a 24-fret bound rosewood fingerboard with dot position markers. Components include a synchronized tremolo bridge and Ibanez pickups in an HSH configuration. The RG185G is a similar model with gold hardware and a pickguard and without the quilted maple top. The RG198QM was available only in Japan and was discontinued after 2000.
