High Quality Content by WIKIPEDIA articles! The Yamaha RGX Series electric guitars are manufactured by the Yamaha Corporation and bear 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.
