Hello together I’m stuck at the moment on finding the right mouthpiece. I would like to share my experience until now, in order somebody had a similar experience or can give me a tip. So, I started my journey with a Denis Wick (DW) 4b. I realized soon, that this mouthpiece is not very comfortable. And also the sound I produce with it is very tight (especially high tones, from a’’ on) Then I tried an Yamaha 14E. Much more comfortable. It sounds better (the sound I produce). But when playing high parts for some time, the sound becomes more airy and the airblow is getting worse. It feels as the air can’t get trough) Next I tried a K&G 2C. That thing has a really great sound. It’s what I want. Airblow also great and also Intonation. It has everything I want. Negative; For playing high parts it’s very tiring to play, it needs enormous endurance. So then I tried the 2B with not such a deep cup. That solves my problem about endurance. Conclusion until know; it seems like my lips need a big cup diameter, since I can’t handle smaller ones. My lips seems to swell when playing high tones for some time, hence I need more place. The only problem I have with the K&G 2b is, that when playing fast parts with my tongue (for example sixteenth-notes), the sound gets airy, the playing dry and hence also uncomfortable, which is not with the 2c. So I’m stuck know. It seems like the cup should be only a little bit deeper, since that is what differs from the K&G 2C. But since I can’t find in the internet any Data Sheets for K&G mouthpieces, I don’t know what trying next? I’m tending to try the DW 3B or the DW 2BW What do you think?
