The JEMJRSP is a solid body electric guitar introduced by Ibanez in late 2017. It is a signature model of American guitarist Steve Vai and part of Vai's JEM series. It is a special edition of the standard white JEMJR.
As with all JEM models the body features Vai's signature monkey grip on the upper body and lion's claw rout behind the tremolo. Differences from the standard JEM Jr. are limited to the pickups, and pickguard and finish colors.
The JEMJRSP features mahogany body bolted to a maple Wizard III neck with a 24-fret rosewood fingerboard with white Tree of Life vine inlays. Components include pink Ibanez Infinity pickups with a pair of humbuckers flanking a single-coil, a double locking tremolo bridge, a locking nut and an angled output jack.
For 2018 the rosewood fretboard was replaced with jatoba. Later in 2018 the mahogany body was replaced by meranti.
The RG450DX is essentially the same guitar minus the monkey grip, lion's claw routing and angled barrel jack and with different fretboard inlays.
