The predecessor company to Vega was founded in 1881 by Swedish immigrant Julius Nelson, C. F. Sunderberg, Mr. Swenson, and several other men. Nelson was the foreman of a 20-odd man workforce (which later rose to 130 employees during the 1920s banjo boom). Nelson, and his brother Carl, gradually bought out the other partners, and incorporated in 1903 as Vega (which means star). In 1904, Vega acquired banjo maker A.C. Fairbanks & Company after Fairbanks suffered a fire, and Fairbank's David L. Day became Vega´s general manager.
Vega built banjos under the Bacon trademark, named after popular banjo artist Frederick J. Bacon. Bacon set up his own production facility in Connecticut in 1921, and a year later wooed Day away from Vega to become the vice president in the newly reformed Bacon & Day company. While this company marketed several models of guitars, they had no facility for building them. It is speculated that the Bacon & Day guitars were built by the Regal company of Chicago, IL.
In the mid-1920s, Vega began marketing a guitar called the Vegaphone. By the early 1930s, Vega started concentrating more on guitar production, and less on banjo making. Vega debuted its Electrovox electric guitar and amplifier in 1936, and a electric volume control foot pedal in 1937. Vega is reported to have built over 40,000 guitars during the 1930s.
In the 1940s, Vega continued to introduce models such as the Duo-Tron and the Supertron; and by 1949 had become both a guitar producer and a guitar wholesaler as it bought bodies built by Harmony. Vega also produced various amplifiers during the 1950s and 1960s, many of which featured tube chassis. The A series of amps produced in the late 1950s and early 1960s appear to be the most popular. In 1970, Vega was acquired by the C.F. Martin company for its banjo operations. Martin soon folded Vega's guitar production, and applied the trademark to a line of imported guitars. Ten years later, Martin sold the Vega trademark rights to a Korean guitar production company (source: Tom Wheeler, American Guitars).
Banjos currently built by the Deering Banjo Company. Originally, Vega guitars and amps were produced in Boston, MA and instruments were later produced in Korea.
