A very special year for the Duo Jet, 1957 is the only full year that featured both hump block style fingerboard inlays and DeArmond pickups. This is also the much sought after version that George Harrison played leading up to 1963. This particular guitar also has a Bigsby like Harrison's Duo Jet; in this case, it was added after the fact and includes a dogbone bridge. It has also had a refret, finish touchup on the top, a repaired bass side crack, and some binding repair. Comes with its original patterned hard case.
