Coast Wholesale Music Company from the San Francisco Bay Area was an importer and wholesale distributor of musical instruments. They focused predominantly on importing instruments (guitars!) made in Japan to the United States in the 1940’s through the 1960’s. The company was purchased by Charlie Kamam of Kaman Music around 1968, along with Coast Wholesale of Los Angeles — a completely separate company in Southern California with the same name — and C. Bruno & Sons of Texas.
Kaman Music Corp. would later introduce the line of Ovation guitars.
