 Conn.

Jazz trumpet player Maynard Ferguson and Holton (now a division of C.G.Conn) worked together to develop Ferguson's first trumpet, Model ST302.The designer of that trumpet, Larry Ramirez, spoke to Ferguson about a valve/slide trombone that he had designed some 12 years earlier, and this eventually led to Ramirez designing a new valve/slide trombone for Ferguson, called the Superbone, in October 1974.
