The Ibanez RG420FBZ electric guitar features and Ibanez Edge Zero II tremolo with the Zero Point System, tuning stability is maximized. The zero point system in combination with the Ibanez Edge Zero II tremolo system makes tuning easier and faster and provides a stable tuning for long performances while maintaining smooth tremolo playing. Loss of tuning is kept to a minimum even when a string breaks. For guitarists that prefer a full floating tremolo system simply remove the stop bar. An additional outer pair of springs with the zero point sytem provides easier tuning and better tuning stability than the traditional floating tremolo, and spring tension can be quickly set by thumb with no need for a hex wrench.
