This not only has the articulated C#/G#, but also has the left hand Ab/Eb key. So this is a very special instrument.
I noted that the metal lining of the middle tenon made it so that the wood holding one post is very thin. Because of this, that post that may easily become too loose. This in turn can make it tricky to the maintain the delicate adjustment of opposing springs for the articulated key. Also, the male part of the same tenon has a hole in it, and it is very easy for the wood below that hole to break away.
I thank Nophachai for allowing me to review this instrument.

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 0mm. I would want a shorter barrel for this horn.
Intonation summary: Really good. Professional level, and probably better in some ways than the standard Boehm system clarinets of the same period.
Key work quality: Very nice.
This clarinet is most appropriate for: Professional jazz musicians evidently like this model. But anyone who wants an Albert system would love this.
