I have a 28B Constellation trumpet that came without a mouthpiece. I recently picked up a 7B-N Constellation mouthpiece to go with it. I know.... the horn probably came from the factory with something a little more standard line issue. However, got to reading at the Conn Loyalist site and this mouthpiece must have been top of the line back in the 60's. The Conn sales pitch said among other things: (From the Conn Loyalist Site) Connstellation - the first cup mouthpiece design "break-through" in years. A mouthpiece manufactured with incredible precision, far in excess of all previous standards. One that, for the first time, scientifically matches critical dimensions of the rim, cup, orifice length and back bore taper. The result is a new degree of control and flexibility. Plus rigid uniformity from mouthpiece to mouthpiece. Conn's precise dimensional matching also helps to balance tone in all registers, simplify phrasing, increase endurance and range. And the logical coding system greatly simplifies personal selection. Connstellation cup mouthpieces are double plated; heavy silver plate with pure gold overlay. Performer can now attain a new height in tonal beauty... with the unique Connstellation Mouthpieces! I'm happy with it. But I'm a pretty rank amateur trumpet player and the difference between ok and very good is lost on me. So how would it stack up to "professional" mouthpieces of today, do you think?
