The company manufactured and distributed a wide range of instruments – self produced or through its subsidiaries and brands– such as clarinets, saxophones, trumpets, trombones and mouthpieces.

[3] In 1945, Léon Leblanc (1900–2000) met Vito Pascucci (1922–2003), then on duty as the instruments manager and repair technician for the Glenn Miller US Army Air Force Orchestra.

Leblanc's most distinctive saxophones at the time were its Model 100 and 120 "System" saxophones, the latest iteration of instruments designed by G. Leblanc since the early 1930s to alleviate acoustic problems inherent in the standard key system and offer more fingering choices.

In 1981 Leblanc became the exclusive marketer and distributor of the Yanagisawa products in the United States and Canada.

Beginning in 1951, the American Leblanc firm started manufacturing student model clarinets under the Vito brand.

By the late 1950s Vito saxophones were also assembled from parts supplied by the Art Best Manufacturing Company of Nogales, Arizona, with some differences from the Beaugnier designs.

The Vito line of woodwinds was discontinued in 2004, although the equivalent models of saxophones continued to be made by Yamaha and KHS (Jupiter).
