The SC-550 Scroll was the top of the Scroll series of guitars Epiphone made in the late '70s. The SC-350 was an entry level model, while the SC-450 fell somewhere in between. The SC-550 featured an ebony fretboard with block inlays, brass nut, and came with either covered Epiphone humbuckers or open coil Gibson humbuckers (indicated by a G suffix in the model code). The SC-550, like other guitars in the Scroll line, came with either a stop bar/Tune-O-Matic bridge system, or a Leo Quann wraparound bridge.
