This 1957 6120 serial # 22462. has all the traits typical to that year: Horseshoe headstock inlay (replacing steer's head of '54--'56), hump-top block fingerboard markers (replacing the rectangular blocks of '56), and a "Bar" bridge (replacing the aluminum Bigsby compensated bridge of '54--'56). De Armond single-coil pickups were still used in 1957, although they would be replaced in 1958 with the new Filtertron humbuckers Atkins preferred. These twangy De Armond pickups would help to create the signature sound of rock 'n' roll icon Duane Eddy. Eddy purchased a 6120 very similar to this one in October 1957 and went on to have numerous instrumental hits.
