The Gibson Electraharp pedal mechanism was developed to allow quick tuning changes between songs and allowed the player to raise or lower the pitch separately on individual strings. The sumptuous figured maple and walnut case hid the pedals and the player's feet behind an elegant Art Deco façade. According to Gibson's 1942 catalog, the instrument took five years to develop and "not until every detail had been perfected was a working model shown." The Electraharp had been developed jointly by a Gibson machinist, John Moore, and Alvino Rey, a well-known Gibson endorser. The Electraharp was Gibson's most expensive product in 1942, when it was sold for $477—$111.50 more than the most deluxe Super 400 arch-top guitar. Gibson records indicate that thirteen of the instruments were shipped before World War II and a dispute with the Harlin Brothers of Indianapolis, who held the patent on a similar design, the Multi-Kord, caused Gibson to cease production. The Electraharp was reintroduced after World War II mounted on steel legs, rather than built into a wooden cabinet, and with only four pedals. In 1949 it sold for a significantly reduced $395.
