Yamaha RGX

The Yamaha RGX Series electric guitars are manufactured by the Yamaha Corporation and bare a close resemblance to the Ibanez RG series, the Jackson Soloist and other "superstrat" enhanced copies of the Fender Stratocaster. These Taiwan-made instruments were introduced in 1987.

RGX Series guitars often have 24 or more frets and a bolt-on neck. Some high-end models use a neck-through-body design. Some come with Yamaha active pickups, two single coils and one humbucker. Most of these instruments were generally known as RGZ, including the RGZ820R, a custom plaid graphic model with two humbuckers and a Floyd Rose licensed locking tremolo, played by rock guitarist Blues Saraceno. The RGX guitars were upgraded in 2003 with a 3D headstock sporting a 3+3 tuner layout and a piezo bridge option for acoustic-like tones. Famous endorsees of the RGX/RGZ guitars included Blues Saraceno and Ty Tabor of King's X, who got his namesake RGX-TT and RGX-TTD6 signature models in 2000.

RBX Bass Series

The RBX Series are the equivalent bass versions of the RGX line. Introduced in 1987, these Taiwanese-made basses came with active or passive circuitry, a variety of pickup configurations and the choice of 4-string, 5-string, fretted, fretless and left-handed versions. They featured a bolt-on 22 fret maple neck with a rosewood fingerboard and abalone dot inlays, a pointed headstock with 4-in line tuners (4+1 tuner layout on the RBX5 and RBX755A 5-strings), except for the RBX800 and RBX1000 which feature 24 frets and through-neck construction. Only the RBX550 came with an optional maple fingerboard with black dot position markers (RBX550M). The RBX range has been updated in 1998 with a new body style, a 3D headstock with 2+2 (4-string) or 3+2 (5-string) tuner arrangement and a two-octave rosewood fretboard. The RBX6JM and RBX-JM2 6-strings topped the line, endorsed by Dream Theater bassist John Myung, the latter using a single custom-wound Seymour Duncan SMB-6A humbucking pickup, black hardware, an active 3-band EQ and a 24-fret rosewood fingerboard with oval abalone dot position markers.
