Part of Rickenbacker's 600 series, each of which is fashioned into Ric's classic cresting wave body shape, the Rickenbacker 620 electric guitar was initially intended to be an update to the 610 and 615. However, the 620 didn't prove to be as popular as its cousins, the 330 and 360 -- but that doesn't exclude a number of famous players from counting it as a favorite, including Steven Van Zandt and Mike Campbell.
