Conn used to make some of the best saxes in the world. They were the only company to make the mezzo soprano saxophone which was made in the key of F. They also made the Conn-O-Sax which was also keyed in F. It is believed that only 100 of these instruments, meant to substitute for the English horn, were ever made.

Then there are the C soprano saxes which were made to play oboe parts in military marching bands.  This picture is of a Conn C soprano sax next to a Selmer Paris silver Bb clarinet. The C soprano was less than one inch shorter than the more commonly seen Bb soprano sax.

 The Conn microtuner was a very neat and unique invention that allowed for the fine tuning of a sax by turning a knurled knob rather than grasping the mouthpiece, lig, and reed possibly pulling the position sensitive reed out of alignment. Stephen Howard has a very nice article about the microtuner at http://www.shwoodwind.co.uk/HandyHints/ConnMicrotuner.htm. Keeping the microtuner working took some extra work as Stephen details in his post.
