The JCRG-21B is an RG series solid body electric guitar introduced by Ibanez in 2001. It was made in Japan by FujiGen as part of the high end J Custom line.
The most unusual and striking feature is its chambered body with four thin, parallel holes in the top between the two pickups.
The JCRG-21B features neck-through construction with bubinga body wings with a spruce top with white binding attached to a maple and bubinga neck with a 24-fret ebony fingerboard with white binding and a special diamond with wings (or two birds kissing?) inlay at the twelfth fret. Components include a pair of DiMarzio PAF Pro humbucking pickups, a Roland GK synth Divided Pickup, a Lo-Pro Edge double locking tremolo bridge with a locking nut and Gotoh tuning machines. It has both standard ¼" and Roland 13-pin outputs.
The JCRG-21A is a model with similar specs but with mahogany body wings and quilted maple top.
The JCRG-21B was discontinued after just one year in production.
