The first guitars to bear the Westone name were made by manufacturers in East Germany and Italy until 1975, when Japanese company Matsumoku acquired the rights to the Westone name, producing acoustic guitars and copies of some US models.^[3]

St. Louis Music registered the Westone mark in the United States in 1976 to market Matsumoku instruments in the country.^[4] They began importing the Westone-branded guitars to the United States as a replacement for their previous line of Custom Kraft–brand instruments manufactured for them by Kay and Valco since the mid-1950s.^[5]

Electra was also a brand of St. Louis Music. In 1984, they merged both brands to make the "Electra-Westone" brand, before dropping "Electra" from the name entirely from 1985 onwards. The majority of Westone guitars of the 1980s were made by the Matsumoku factory in Japan and imported by St. Louis Music.^[3] With Matsumoku ceasing operations in 1987, production was moved to Korea in 1988 and most of the innovative models disappeared. St. Louis Music replaced the Westone brand name by Alvarez in 1991.

Though initially popularized as inexpensive, entry-level guitars particularly useful for students, the transition to Asian manufacturing in the 80s brought a fundamental change in production, with designers emphasizing features such as custom pickups and electronics. Many Westone guitars and basses have since become collectors items.

In 1998, renowned luthier Sid Poole built some prestige guitars in England under the Westone name. Another revival of the brand came in 2010 when German company Musik-Meyer began producing Weston-branded copies of traditional instruments from other companies, such as the Fender Stratocaster, Fender Telecaster and Gibson Les Paul.^[6] In China, manufacturers have also commercialized copies of traditional US guitars with the Westone brand.^[1]
