The RG1527Z is a seven string 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 and replaced the RG1527. In the USA, this model was often still referred to as the RG1527; the Z suffix is ignored for some models in promotional material.
The main differentiator between the RG1527Z and its predecessor is the new Edge Zero 7 double locking tremolo bridge with removable ZPS3 tuning stabilizer. Other features include a basswood body bolted to a maple and wenge neck with a 24-fret rosewood fingerboard with pearloid dot position markers. Components include a pair of Ibanez humbucking pickups and Gotoh tuning machines.
The RG1527MZ is a similar model with a maple fingerboard.
