The RG4020QM is an RG series solid body electric guitar model introduced by Ibanez in 1996. It was a spot model which was made in Japan by FujiGen. Although it is not designated as part of the Prestige or J Custom lines which originated around that time, the build quality is similar to those models.
The RG4020QM features a thick quilted maple top on a mahogany body bolted to a maple neck with a 24-fret rosewood fingerboard with abalone dot position markers. The headstock sports a rosewood veneer with a inlaid pearloid logo. Components include a pair of DiMarzio humbucking pickups, a Lo-Pro Edge double locking tremolo bridge with a locking nut and Gotoh tuning machines.
Instead of the more typical 5-way lever, the RG4020QM has a 3-way toggle switch for pickup selection. It is among only a small handful of RG models with this type of control configuration which is similar to that favored by John Petrucci on his JPM100 signature model.
The RG4020QM was produced in very small numbers (perhaps as few as 18 or 28) and sold only in Europe and Japan.
