Bsm4x mouthpiece for Yamaha 321

Post by soarcj@aol.com »

The difference between the denis wick 4ay mouthpiece for the Yamaha euphonium and bsm4x is a different rim shape which makes the bsm4x feel more comfortable. Also the cup is just a little less shallow than the 4ay. Is that for the high register? They :tuba: :tuba: both fit the Yamaha lead pipe.

After playing on the denis wick bsm4x mouthpiece on my Yamaha 321 I feel my high regester improved as well as my stamina. I feel that the bsm4x is an improvement over the 4ay.
