What Conn said in 1931:
Present-day bands and orchestras are according a place of great importance to the Eb baritone. The soul-stirring majesty of the pipe organ is found in its vibrant, mellow voice. Saxophone ensembles, even the trio, almost always include a baritone. Besides lending a broad, generous harmony voice in bands and orchestras, it is also an excellent solo instrument and many artists use it for this purpose.
The Conn baritone has been a leader for years and the present baritone is the finest of them all, due to recent improvements and refinements, among them the high E-natural and F keys. Like all Conn saxophones, the sockets are drawn from the body metal and the edges rolled, insuring leak-proof instruments. The Hydraulic Expansion Process of manufacture produces a glassy-smooth inside surface for carrying the delicate tone waves, insuring not only great ease of blowing but surpassing richness of tone.
