If the tone is woolly, then it is not optimal, and therefore the mouthpiece is not optimal, and further design work is necessary to balance the cup, throat and backbore to maintain the warmth while getting rid of the woolliness. And the rim has nothing to do with maintaining tonal characteristics.Neptune wrote:The 24AW is very popular for use with compensated Eb's in the UK both in bands and orchestras. It does produce a good warm tuba tone from Eb's (as you can hear on many recordings), but at the same time IMHO the sound is a bit woolly.
If you could produce an Eb mouthpiece with that characteristic warm tone without the woolliness, then I would think it the ideal for compensated Eb's.
I cannot see any reason why you could not change the rim, while maintaining tonal characteristics
One reason the 24AW is popular is because its throat (at least according to spec, and that is taken with caution, because of the inconsistency of Bach mouthpieces) is 8.84mm, even wider than a Wick 3, so a player can push a lot of air through its reasonably deep cup. However, this may be part of what makes it woolley on a Sov eefer. So something like a 24AW cup, which is deep but not too deep, with a different throat and backbore, may have potential.
And I believe this is just what bloke is trying to accomplish. Hey bloke -- that is an idea: try grafting a 24AW cup with a shaved rim so it doesn't bang your nose onto your standard reverse throat and backbore and see what happens.
Oh, bloke, - BTW - I agree with you on the wide rim. When I first got my Curry 128D, it had a wide rim approaching 24AW, and it did the same thing to me, causing the mouthpeice to ride down and lose centering on my embouchure. I had to have Vladimir @ Dillon Music shave it down to 18 contour. Now it's just right.
So iiipopes, what mouthpiece do you play on your EEb ?
