The RG2120K is an RG series solid body electric guitar model introduced by Ibanez in 2001. It was made in Japan by FujiGen and although it was badged and marketed as a Prestige, its construction, specs and details such as the serial number stamp mark it as being built by the J Custom team.
The RG2120K features a koa veneer top on a mahogany body bolted to a maple neck with a 24-fret rosewood fingerboard with small offset dot position markers. Components include a pair of Ibanez humbucking pickups, a Lo-Pro Edge double locking tremolo bridge, Gotoh tuning machines and Gotoh Free-Lock strap pins.
The RG2120X is a related model without the koa top and with piezo pickups integrated in the tremolo. The RG3120 is a related model with a flamed maple top among other small differences.
The RG2120K was discontinued after 2002. It is believed that fewer than 25 examples were produced.
