The RG370FMZ is an RG series solid body electric guitar model introduced by Ibanez in 2016. A previous model with the same name but different specs had been produced a couple of years prior.

The RG370FMZ features a mahogany body with a flamed maple top bolted to a maple Wizard III neck with a 24-fret rosewood fingerboard with binding and sharktooth position markers. Components include Ibanez Quantum pickups with a pair of humbuckers flanking a single-coil and an Edge-Zero II double locking tremolo bridge with a removable ZPS tuning stabilizer.

For 2018 the rosewood fretboard was replaced with jatoba. For 2019 the mahogany body was replaced with meranti.

The RG370PBZ is a similar model with a poplar burl top and dot position markers
