The ISB was founded by the world-renowned virtuoso Gary Karr in 1967. With some 3,000 members in over 40 countries, the ISB is an organization for those who teach, study, play, repair, build and enjoy the double bass. The ISB is a forum for communication among bassists throughout the world and across a wide variety of musical styles. Members receive our journal, Bass World, three times per year and are the first to receive email communications regarding upcoming events, bass news, and more.
