I haven’t seen any commentary on this new model. Personally I love it.
Doc’s description is right on. Has no one else got their hands on one of these?

The Onyx has been very well received. If you do a search using “Onyx”, you’ll find a few reviews and comments.
I have the Onyx and really like it. It’s an easy stretch and the ornaments sound crisp and fast. I also like the tone, which a little on the reedy side. Great Whistle.
