Jack Westheimer, one of the early pioneers that brought Asian made guitars to the U.S., set up business connections with Japanese guitar makers in the 1960s with the intention of importing Japanese made guitars into America. Some of the brands that Jack Westheimer worked with were Pearl, Silvertone, Cortez, Kingston, Cort and many others. In 1973, Jack Westheimer founded the Yoo-Ah Co. The Yoo-Ah company would eventually be called Cor-Tek which was named after Jack Westheimer's Cortez brand name. Cor-Tek manufactures Cort branded guitars.
