The most noticeable feature of the RG652K is the Australian blackwood top on a basswood body and matching marbled rosewood fretboard. It also features an Edge double locking tremolo bridge, dual DiMarzio humbucking pickups and Gotoh tuning machines. The RG652KFX is a very similar model which differs only in that it has a fixed bridge. The RG652AHM is another version with an ash body and maple fingerboard.
