J. Max and Everyone,
I'm a big fan of the Morgan 3C. As I've mentioned in other threads there are times when I'll visually study Ralph's design features of my 3C and try to figure out how it plays as magically as it does. Since I'm not doing as much classical playing as I did in the past -- mostly big band now -- my main piece has become a 6L....which works beautifully on my New Aristocrat.
I'm in the process of trying an experiment with my 3C. Around 4 years ago Ralph Morgan custom made a 6C piece for my '28 Buescher TT soprano. Hands down, it was the very best soprano mouthpiece I ever played and it was a great match for my Buescher. Spot on intonation. Since I'm feeling so comfortable with a 6 (.090) facing on my tenor set up, I decided to have Ralph Morgan open my 3C tenor piece to a 6C. I'll let you know how it works out.
I agree about the differences between the early Bilger-Morgan pieces and Ralph Morgan's current work. I have a Bilger-Morgan tenor piece in a 6 facing that was made in 1985. These early pieces were made from Babbitt Company blanks. It has a huge dark sound. However, it lacks the vibrant tonal qualities and superb response that I've come to expect from a Morgan. A big part of this difference is the very high quality hard rubber formula that Ralph uses -- miles apart from a Babbitt blank. It will be interesting to compare the 6C when it arrives with the Bilger-Morgan.
