I thought I remember the NAMM headquarters in Chicago, is this correct?

NAMM was formed in 1901 in New York. After several difficult years during the Great Depression, NAMM closed its New York doors and re-opened in Chicago. While in Chicago, the industry enjoyed great growth and NAMM's many music programs, such as AMC, flourished. NAMM's headquarters were relocated to Southern California in 1984, where the current building was established in Carlsbad (in San Diego County) in 1997.
