This clarinet is from the World War II era when it was difficult to get African black wood. If I remember correctly, later Conn Pan Am instruments were beginner instruments in the same league as Bundy horns.
Bore LH joint top: 15.25mm (wide bore)
Bore LH joint at bottom: 15.0mm
Intonation results taken when playing loud and not lipping. See how to interpret these results on the Wooden Clarinets main page.
This seems to play better without a barrel ring and pulled out 2 mm. This helps bring down the sharp throat tones. Tested with a Portnoy BP3 mouthpiece and a Legere 4 reed.
Intonation summary: This is a horn that was made in the big band era, and it will most happily play in jazz contexts. The sharp throat tones A and B-flat can be brought into tune with resonance fingerings. The sharp Chalemeau register is typical of large bore instruments.
Key work quality: This has German key like the Conn Director. Hey, this can't be German key work if this was made during the WWII era! Maybe this was made all in America, as the name might suggest! I don't like the key work on these instruments. The set screws for the pivot screws are not really needed, as shown in other clarinets. And the key work has some sloppiness in it that is a contrast to the care taken to add set screws. I have experienced breakage with such Conn keys.
This clarinet is most appropriate for: Adults in jazz bands. This is also a collectible clarinet.
