My usual horn is the Model 228 Lightweight 400 and I use the Al Cass 1-28 reissue with it. Fabulous combination, I sound pretty good on it.
For my next concert, I want to use my Model 240 Custom Built:
(Wouldn't you want to use this gorgeous horn too?)
The thing is, unlike the other Buescher horns I own, this is a medium bore horn that plays somewhat tight. With the Al Case piece, it's a lot more resistant than the Model 228 is.
But! The Buescher Duo-Cup 88-D mouthpiece is the same diameter with a much larger throat and backbore, and wouldn't you know, that combination just sings! It also explains why those mouthpieces have such large throats and backbores.
I have a particular 88-D that has a rim and diameter not terribly different than the Al Cass piece. Not exactly the same, of course.
I could do one of two things:
- Use the Al Cass piece and adapt to the tighter blow
- Use the Buescher piece and adapt to the different rim
At this point, I'm going to use the Buescher piece and adapt to the different rim because it bothers me less than the different blow but I'd be curious others would do.
