Gibson Moderne

The Gibson Moderne is an electric guitar model prototyped by Gibson in 1957. It was designed alongside the Flying V and Explorer as part of a stylistically advanced line of electric guitars. However, unlike the Flying V and Explorer, the Moderne was not put into production until 1982.

Because few prototypes were made in the 1950s, and no authenticated example is currently known, the hypothetical 1958 Moderne has been called the "mythical great white whale" or "holy grail" of collectible guitars.
