This RB830 Roadstar II was made in Japan and wears Caiman Green, a colour offered on the RB830 for the 1987 model year. The neck heel and neck pocket carry matching RB830 / RB830B and CG / C.G. markings, alongside a SAMPLE mark. That mark points toward a pre-production or approval sample, but its exact original purpose cannot be established with certainty.
The protected finish inside the neck pocket has kept a different shade from the exposed surfaces, making the bass's natural colour shift easy to see. Its PJ pickup layout, 24-fret board, Accu-Cast BII bridge and unusual original strap retainers are documented in the photographs. It comes with a vintage Ibanez gig bag.
Inspection & research notes
Inspection notes record stable neck, functioning electronics and hardware, with only minor marks; no major dents, cracks or structural issues have been noted.
The SAMPLE marking is interpreted as a likely pre-production or approval sample; the exact role remains unconfirmed.
