The HRG4 (or HRG04) is a seven-string RG series solid body electric guitar introduced by Ibanez in 2005. It was made in Japan by FujiGen as part of the high end J Custom line. The HRG4 was a spot model created exclusively for the Japanese retailer Ikebe Gakki.
The HRG4 features a South African mahogany body with a AAAA grade quilted maple top bolted to a maple and wenge neck with a 24-fret rosewood fingerboard with pearloid Tree of Life inlays. Components include dual DiMarzio PAF7 humbucking pickups, an Edge Pro 7 double locking tremolo bridge with a locking nut and Gotoh tuning machines.
The HRG4 was offered only in 2005 and just 15 examples were produced.
