The Gibson Super 400 is an archtop guitar. It is a highly influential guitar model that inspired many other master guitar builders (including Elmer Stromberg and John D'Angelico). It was first sold in 1934 and named for its $400 price, like many Gibson guitars of that era. In 1939 the guitar was changed. The upper bout was enlarged, and the hand-engraved tailpiece was replaced with the one still fitted today on current Super 400s. The f-holes were slightly enlarged and a cutaway option also became available. This was called the Super 400P (for Premiere), later changed to C for Cutaway.
