The ZPS3 is the next stage of zero point systems. Made of lightweight Duralumin, the addition of two outer springs makes the guitar easier to tune and provides much greater tuning stability. In fact, the other strings will stay in tune even if you break a string. If you prefer a full floating tremolo setup, simply remove the stop bar. The Edge-Zero has a sharp knife-edge for extremely accurate tremolo playing. This tremolo also uses Ibanez innovations to keep string action constant and the bridge surface smooth. The specially designed arm socket prevents unnecessary wobble from the arm while providing full control over the arm's torque. The DiMarzio® Air Norton™, True Velvet™ and Tone Zone® pickups offer depth, warmth and rich dynamics when combined with the 5-way pickup switch. RG j.custom Super Wizard 5pc Maple/Wenge neck includes jumbo frets finished with j.custom special fret edge treatment for a super smooth and comfortable performance. The "Velvetouch" finish on the back of the neck ensures a "just right" feel and easy playability. This model has AAA Flamed Maple top with beautiful natural body binding and selected Macassar Ebony fretboard with Flamed Maple binding and Tree of life inlay.
