This is a beautiful Rickenbacker 4003 Bass finished in Rickenbacker's signature natural clear coat, known officially as Mapleglo.
Since you noted it is from the 1990s, this is a prime era for the 4003, which Rickenbacker introduced to replace the legendary 4001. The 4003 was specifically designed with an updated, stronger dual-truss rod system engineered to handle the higher tension of modern roundwound bass strings.
Neck-Through Design: Like most high-end Rickenbackers, it features a solid maple neck running continuously through the center of the solid maple body wings. This construction is paramount to the legendary, piano-like ringing sustain that Rickenbacker basses are famous for.
The Finish: The Mapleglo finish beautifully showcases the natural grain of the maple body and neck.
Fretboard and Details: It features a thick rosewood fingerboard adorned with Rickenbacker’s iconic pearloid "triangle" (or shark fin) inlays. Because this is the standard 4003 model (and not the stripped-down 4003S), it features elegant white binding wrapping around both the body and the neck.
Hardware: It is equipped with heavy-duty Schaller deluxe machine heads, the massive cast bridge/tailpiece assembly, and the classic chrome pickup cover resting over the bridge pickup.
The Rickenbacker 4003 is renowned for its aggressive, punchy, and highly articulate "clank" that cuts perfectly through heavy rock mixes.
Pickups: It is equipped with two Rickenbacker High-Gain single-coil pickups.
Controls: The layout features individual volume and tone knobs for each pickup, governed by a 3-way toggle switch mounted on the white pickguard.
Ric-O-Sound: Looking closely at the bottom edge, it features Rickenbacker's famous dual-output jack plate. One jack is for a standard mono cable, while the other is the "Ric-O-Sound" stereo output. Using a specialized splitter box, this allows you to send the neck pickup to one amplifier (for deep bass) and the bridge pickup to a completely different amplifier (for overdriven bite).
Rickenbacker 4003 basses from the 1990s are highly prized workhorses, and Mapleglo is one of their most enduring and popular finishes.
Used Value: Judging by the photos, this instrument appears to be in exceptional, remarkably clean condition for a 30-year-old bass, and the inclusion of the original blue-lined molded hardshell case adds significant appeal. On the current vintage/used market, an excellent condition 1990s Rickenbacker 4003 Mapleglo commands a value solidly between $2,300 and $2,800.
