I found this phonograph needle organizer at a thrift store. It brought back memories of having to buy new cartridges to keep the vinyl records sounding good.
Founded by Lou Borroughs and Albert R. Kahn in South Bend, Indiana in 1927, Electro-Voice pioneered a number of important audio technologies. During World War II, they came up with differential noise-cancelling, which they licensed to the U.S. government for free. In 1946, they began manufacturing phonograph pickup cartridges. They were also big in the microphone and speaker markets. The company was bought and sold a number of times, and is now part of Bosch Security Systems.
