Re: BD4 Throat Design?

Jeroen,

Wow, that's surprising. I know that Vandoren mouthpieces may vary a bit because they are hand-finished (at least on the baffle), but your BD4 is REALLY different from mine--pretty much like my BD5 and BD7.

I have 2 BD4s purchased within the last 6-9 months and they both have a very dramatic ledge between the throat and the baffle--unlike anything I've seen in any mouthpiece.

When did you receive your BD4? Perhaps Vandoren has changed the design?

Perhaps I should order a couple more for evaluation.

Unlike a drop from the throat as the air moves into the bore (which I would imagine would result in a lowering of air pressure/speed), perhaps the raised ledge as the air moves against into the throat would increase air pressure/speed. My thought is that it might also introduce turbulence, which one might expect would have an adverse impact on the power/focus of the tone. However, the BD4 seems to have MORE power and focus, and a slightly more brilliant sound that either the BD5 or BD7.

Oh well, now I'm really perplexed...
