Barrel: Two included: 62.9mm which I will use for this test, and 64.5mm.

This clarinet is obviously made by the same Chinese company as the Ridenour. That evidently company makes both plastic and hard rubber and plastic clarinets, since Ridenour sells clarinets made of both marterials. I think that the Tyro is plastic with a hard rubber barrel, like Tom’s 146.
One of the best parts of this clarinet is the excellent zipper case. Too bad the clarinet is so out of tune.
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 1.1mm at the barrel and 0 in the center for this horn.
Intonation summary: Awful.
Key work quality: Excellent. The crow foot is not quite as thick as the Ridenour.
This clarinet is most appropriate for: This will only work for a beginning clarinet player for one year.
