Al CASS MOUTHPIECES

[trumtrumtrum]

I'd like to start a little discussion about Al Cass mouthpieces.
I'm happy if anyone likes to join...

To start with, here are the models that I currently have...

Al Cass originals:
1-28-28 trumpet
1-26A trumpet
1-25 trumpet
3 flugel
1-4E flugel
trumpet to french horn doubler
trumpet to trombone doubler

Made in England:
L1 trumpet
4x1 trumpet
3x3 trumpet

Steve Cass replica:
1-28 trumpet
3x1 trumpet
4s1 trumpet

I also had an 3x5, 3x7, some cornet and trombone pieces and two Diz Cup mouthpieces.

I primarily use the 1-28 and the Flugel 3 since roughly five years and they work just great for me.
In the begining it took me some time to get comfortable with them after playing a Bach 5C for about seven years.
But ever since I never got back to the Bach.

So who else has some Al Cass pieces and likes to talk about them?
