Thanks to Kevin and Lauren Hearne for giving me the chance to review this!
Bore LH joint top: 15.5mm HUGE!
Bore LH joint at bottom: 15.0mm poly-cylindrical!
The Conn Director USA seems to have been made in Germany. I gather this because of the style of keys and the set screws. The keyed joints are hard rubber.
Intonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.
For this test, I pulled 3.2 at the barrel and 1.5mm at the center tenon! Wow! One would never have to worry about being flat.
Intonation summary: The intonation is wonderful, even pro quality. The reason is because this seems to be an early poly-cylindrical bore instrument. The plastic barrel gives a plastic sound.
Key work quality: The keys are very clunky in appearance. But they are thick and sturdy. Note that this clarinet has the German set screws, and this is a sign it was made in Germany.
This clarinet is most appropriate for: Anyone, but especially beginners.
Condition issues noted: none.
