FYI: Rossi offering two types of throat Bb mechanisms

FYI:

I saw that Luis Rossi is offering two options for a throat Bb mechanism on his clarinets, so I wrote to him to get the details. Here is what I received (with some spelling corrections):

"Regarding the 2 options for the Bb mechanism: some people can not get used to the required LH thumb action for the model 1. They are only a few, I must say. With this model , if you do not clear well the thumb ring, then it affects the action of the Bb vent hole.

The model 2 is attached to G# key, so it does not involve the LH tumb. But the spring for G# key has to be a bit strong, in order to close the whole mechanism. Still playable, of course, I am mentioning you all details.

Some players prefer model 2 for using alternative fingerings for the altissimo. One example is : if you want to play top E sharper by uncovering the LH thumb chimney, with model 1 is not possible because the Bb venthole is attached to the thumb ring and will also open. But with model 2, it is possible, since G# key will remain closed.

I used both of them with good results."

Cheers.

P.S. I have no business relationship whatsoever with Luis Rossi. I just like him and his clarinets.

"With this model [1], if you do not clear well the thumb ring, then it affects the action of the Bb vent hole."

I have this model on my Bb clarinet, and this is the issue that is taking some time to get used to. I don't believe, however, that the adjustment is that onerous...in reality I simply have to be more accurate.

The mechanism greatly enables the production of the throat Bb. It sounds much more like the A key/Second Trill key fingering that often produces a Bb that sounds full. That being said: on my instrument the A key/Second Trill key produces a slightly better Bb overall.
