Quick DE question

Doug, or DE fanatics, I see that the EUPH, SYM, XT, SB, LB , etc etc all have options for 8 and 9 shanks, among others. I know that each shank also needs to have the cup letter designation.

My question is, are the shanks cup specific, rather than series specific? In other words, is a J8 shank compatable with the SB J, XT J, and EUPH J cups and the same shank regardless of what series you order from?

Bonus question: Would there be any reason to try a "9" shank if I don't play a dual bore instrument? I always wish shallow large bore mouthpieces played "louder" (with the exception of the 4CL which has the largest throat and backbore) but I imagine the "9" shank wouldn't be the solution to that? For example, an XT E cup, intended as a solo mp for large bore, wouldn't become louder or more projecting with a 9 vs 8?

As far as I know the shanks are not series specific. They are mated to cup depth, so an E cup plus D shank is too long (although not that much in this particular case).

I don't even own a 9 shank so I must duck your second question.

Shanks are letter specific, not series. Yes, you can use a G8 shank with a LB G or an LT G cup, for example.

For the 8 or 9, that is a question best for Doug. Walk him through your thought processes and similar equipment you have liked and he'll have a point of view that will be helpful.

Cheers,

Correct: Shanks are letter specific, not series. The excepts are most of the "plus" cups work best with the next letter shank - B+ takes a C shank, C+ takes a D shank, D+ takes an E shank. G+ has its own G+ shanks.

As to the 8 vs 9 backbore: 8's are supposed t be best on "most" horns, and 9's are a different design intended for dual bore specifically. I also now have #10 backbores for some of my cups. They are intended for very strong symphonic players who need to put out a lot of sound. I think they work equally well on single and dual bore, for those players who can handle them. I'm continuing to improve all of my mouthpieces, and backbores marked with a star are new designs that have better focus and feel more open. The D8* and E8* are now worth trying if you want a shallow mouthpiece on a large bore horn.

Thanks Doug! So some symphony players might even use, say, a G10 backbore? Or that's the idea anyways?

That's the idea, but I'd like to spend a little more time on it myself - still experimenting.

Thanks Doug!

The reason why I like to ask questions to Doug here rather than in a private message is that he is an admin here, and now this good info is available to be searched.

The ability to search and find this kind of info is invaluable to those of us mere mortal trombonists :good:

How about rims and cups? Can a XTK cup fit a MB/LB rim?

The diameter where the cup meets the rim is different between the series. Match an LB rim with an LB cup.

The rule is that the series has to be the same for the rim and cup, for two reasons - the threads need to be the same (tenor and bass use different threads) and the inside interface diameter (rim to cup) needs to be the same.

I see! I thought it would be something in that order.

Thanks for the answers!
