The RX180B features a plywood or mahogany body with a flame maple top bolted to a maple neck with a color-matched headstock and 22-fret rosewood fingerboard with dot position markers. Components include a synchronized tremolo bridge and Ibanez pickups in an HSH configuration. The RX175B is a similar model without the exotic top. The RX180B was sold only in Japan and was discontinued after two years in production.
