Production of other wind instruments remained in Elkhart. The late 1960s saw trends in the keyboard, wind, and stringed instrument markets that were seriously undermining C. G. Conn's position. The growing popularity of portable electronic keyboards was cutting into C. G. Conn's niche of home organs and pianos. The market for student instruments was becoming increasingly competitive, with newcomers from Japan offering products more efficiently produced, with higher quality standards, and more tailored to students' needs. Conn saxophones had ceased to be competitive in the professional market during the 1950s due to outdated designs and declining quality. By the late 1960s, their student line instruments were in competitive decline for similar reasons. By 1969, C. G. Conn, Ltd. was facing insolvency. Company from 1969 to 2003 In 1969 C. G.

First to go were the failing electric guitar venture, which was discontinued, and Conn Keyboards, sold to Kimball. Henkin hired Tonight Show trumpeter and bandleader Doc
