C.G. Conn was always a company with great vision. In the late 20's and throughout the 30's Conn under went an almost renaissance-like bliss in their production. The Conn-O-Sax and the F-mezzo saxophones are great examples of the Conn's creativity. They were always striving to be on the cutting edge of new technologies and ideas.

In this tradition, Conn established the C.G. Conn Ltd. Experimental Laboratory in 1928 to to out distance their competitors in the scientific development of musical instruments. Carl Greenleaf's son, Leland Burleigh Greenleaf (1904-1978) was head of the labratory and Allen Loomis (1877-1948) was the chief engineer.

Included among the many achievements generated at the Conn lab were the wireless and rimless Vocalbell (1932), the first successful short action valves (1934), and the first electronically formed, one-piece seamless bell, later know as the Coprion bell (1938). The most famous invention that was created at the Conn Experimental Laboratory was the Stroboconn, the first device for the visual measurement of sound.

The lab closed it doors in 1940 as Conn began to loose marketshare and competition forced an more streamlined production.

In what year was the Stroboconn invented??
