Dear Sirs!
I´m an Austrian craftsman an appreciate the work of Vincent Bach!
Your website is great and extremly interesting.
Just now I have got a Bach mouthpiece for restoration. It is a 1 1/4 C but the fraction stroke is horizontal. You describe many periods but not the different in the fraction bar. Do you have an idea in which period this mp had been produced? The dealer was “Lechner Bischofshofen”. This shop was founded in 1988. Regards, Karl
I added some additional images of fractions. Check out the Mt. Vernon images from 1960-1965 above for a reference.
Hi, do you make bach mouthpice for french horn?
Yes, Conn Selmer makes Bach french horn mouthpieces. Go to your local music store to find a selection.
it doesn’t exist this mouthpiece…i want Bach mouthpiece for french horn, but to be changed, modified….i want Bach 10, but with narrow rim, with medium cup depth, end 17.70 mm cup diameter. I wish it for medium high register horn…you can do this type of mouthpiece?
You’ll need to connect with a mouthpiece modification type company to have modified to what you want. Have you ever worked with Dillon Music in NJ? Dillonmusic.com
If not, you’ll have to work with your local store repair shop to see what they can do for you… This website is more for history, and information on Bach instruments, not about modifying equipment…
Hope this helps
Hi! I’ve got a Vincent Bach Corp., New York trumpet mouthpiece, size 6, with a small capital M directly under the 6 on the throat. MP also has a ’20’s style slanted (as opposed to square) rim. 1) Is this MP from the mid to late ’20’s? 2) What does the M on the throat stand for? Thanks! – Don
I’ve not seen that marking before. More than likely an indication of the back bore configuration.
Send me an email with high resolution photos and I’ll look more into this. Please send to admin (at) bachloyalist.com
There’s a rumor going around, that some of the newer Bach mouthpieces are produced in China, and that you can tell which ones by looking at the typeface on the piece. This sounds strange to me, but could there be some truth to it?
Hello,
I have a “VINCENT BACH CORP.” (with a dot) 7DW mouthpiece with RK engraved after 7DW. Does this mean something (I do not find anything about this in Bach catalogs) or could it be a personnal engraving of the previous owner?
Thanks a lot.
So I was handed down a mouthpiece when i started playing and it’s very strange to me.It’s a Vincent Bach Corp. Mt.Vernon N.Y. That’s all that’s listed, no cup size. its extremely shallow on the inside and rounded to the little hole even, not cupped. I’m a high school student so I’m no genius.
