Yamaha Mouthpiece Trumpet 11B4

Started out with the Yamaha 14B4 that came with my Yamaha 5335 trumpet. But after a couple of months I felt a bit restricted in the upper register. I like the Yamaha rim shape with slightly softer inner edge compared to Bach. So I ordered the 11B4 to try out. I must say that made all the difference for me. I feel very relaxed playing for longer periods. The tones snap in easily and the sound is great. I still use the 14B4 now and thenwith its slightly warmer tone and the 14E4 with the dark flugellike tone. But the 11B4 is my go-to-mouthpiece for shure!
