The RG7421 is a seven string RG series solid body electric guitar model introduced by Ibanez for 2013. It is essentially a seven-string version of the RG421. It is produced in Indonesia.
The RG7421 has a basswood (later mahogany) body bolted to a maple Wizard II-7 neck with a 24-fret rosewood (later jatoba) fingerboard with white dot position markers. Components include a fixed bridge and dual Ibanez humbucker pickups.
For 2015 mahogany was substituted for basswood as the body material. For 2018 jatoba replaced rosewood for the fretboard. For 2019 the mahogany body was replaced with meranti. For 2020 the bridge was changed to the F107.
A similar model with a tremolo bridge is the RG7420. A version with an exotic poplar burl top, the RG7421PB, was also offered.
A guitar with the same model number was a previously available between 2000 and 2003.
