"The Vega Company was a musical instrument manufacturer that started operations in Boston, Massachusetts in 1881. The company began under Swedish-born Julius Nelson, his brother Carl, and a group of associates that included John Pahn and John Swenson. The founders had previously worked for a guitar shop run by Pehr Anderberg that made instruments for John C. Haynes, another Boston musical instrument company. Nelson had served as foreman of guitar and mandolin manufacturing at Anderberg's shop. Subsequently, Julius and Carl Nelson bought out the other founding associates and established the Vega company. . . .
Perhaps the most visible Vega instrument in the 1950s and 60s was the long neck 5-string banjo designed and used by folk singer Pete Seeger, and later by several folk groups like the Kingston Trio and The Limeliters" (Wikipedia).
