The Ibanez S series first appeared in 1987. Ever since, it has changed in appearance and function to represent the cutting edge of Ibanez design. Famous for its lightweight carved mahogany body, the S can take a beating while still providing the resonance of guitars twice its size. The S series also comes equipped with the ZR tremolo system, a smooth ball bearing tremolo that makes every subtle nuance of whammy bar use come alive. The 7-string version of the Zero Resistance tremolo found on the S7420 features the same ball-bearing based system for precision and friction-free action.
