The RG1550MZ is an RG series solid body electric guitar model introduced by Ibanez in 2010. It was made in Japan by FujiGen as part of the upscale Prestige line.
The RG1550MZ replaced the RG1550M, with the major difference being a new tremolo. However, in the USA the RG1550M name is still applied to this new model, as the Z suffix is ignored for some models in promotional material. It is considered to be in the lineage of the classic RG550.
The RG1550MZ features a basswood body bolted to a maple and walnut neck with a 24-fret maple fingerboard with small black dot position markers. Components include Ibanez pickups mounted in a black pickguard with V7 & V8 humbuckers flanking an S1 single-coil, the newly introduced Edge Zero double locking tremolo bridge with a removable ZPS3 tuning stabilizer and Gotoh tuning machines.
