I read a lot about these mouthpieces, I also looked at the comparator, but I don't agree on the backbore. My 14b4 has a back bore similar to 3C in the beginning, but then it widens towards the bottom. Same thing for BS Jazz. BS Jazz has a slightly smaller backbore than 14b4 and 3C. The holes of all three are exactly the same, but the 14b4 is slightly more flared in the beginning.
Maybe it depends on the consistency (or inconsistency) of the 3 mouthpieces.
Consider that I have 3 14b4, 3 BS Jazz and 4 3C and they all seem to have the above characteristics. |

Nothing, just the comparator shows backbore different from the ones I have.

| I don't think that any mouthpiece comparator is going to tell you how the mouthpieces will compare when you, as an individual, play them. You need to have them in your hand, and play them. Then you can compare them. Otherwise, you can't. The comparator won't tell you how the mouthpiece feels, sounds, or plays. You might as well look at the manufacturer's specs, and get an idea of the width and depth of the mouthpiece. That is a good starting point. Then you need to play them to see if you like them. |

Your comment has piqued my curiosity -- unless you cut your mouthpieces in half (lengthwise) or made a wax casting of their backbores, how could you possibly know this? Or are you just saying that your mouthpieces play differently than what you would expect from the backbore diagrams in the comparator (as Irving is perhaps surmising)?

If you are comparing these mouthpieces then I would certainly try the Schilke 14B as it has a #26 throat which is larger than the #27 on the Bach and the rim feels more forgiving for me. I spent considerable time on the BS Jazz and have also tried Yammy's 14B4 but but keep returning to the 14B Schilke. It's a much better mouthpiece for me. Yammy's do feel slightly smaller on the lips than the Schilke 14 size.

Sorry - are you saying that you measured the backbores using the same technique Vennture uses and you get different measurements? Or are you saying that the Shew does not play like it has a smaller backbore than the Bach? |

| What is not clear? I measured the blackbores using high precision machinery. I don't know Vennture. |
