The RG870Z is an RG series solid body electric guitar model introduced by Ibanez in 2011. It was made in Indonesia as part of the mid-level Premium line. In some cases, notably in the US, it was referred to as simply as the RG870.
The RG870Z features a basswood body bolted to a titanium reinforced maple and walnut neck with a 24-fret rosewood fingerboard with offset pearl dot position markers. Components include newly developed Ibanez CAP-VM pickups with a pair of humbuckers flanking a single-coil and an Edge Zero II double locking tremolo with a removable ZPS stabilizer.
The RG870SPZ is a similar spot model with a flat black finish. The RG870QMZ is a similar model with a quilted maple top.
This was one of the initial models in the Premium line which are produced from higher grade materials and components in a separate facility from other Indonesian models.
