Bach 10.5C - Amazing Piece?

jadickson · Posted: Thu Mar 23, 2023 1:18 pm Post subject:

During the Mt Vernon era, the 10.5C was the second most popular mouthpiece. 7C was first. This according to the Bach mouthpiece manual from that time, of which I have a copy.

And most people say the Mt V and Curry are smaller than the modern ones.

[I have looked on eBay and no one has dates of production listed on the 10.5 C's unfortunately.]

Look for VINCENT BACH CORP 10-1/2C. That should be the production years 1965-1969.
Check out Bach Loyalist. There are pictures of mouthpieces from different eras and you can see what you are looking for.

I have an all original, Mt. Vernon Bach 10 1/2C trumpet mouthpiece in excellent condition. It feels a little smaller than a later 10 1/2C, but has a very comfortable (for me) rim.

I can play it for about 20 minutes and then it stops working for me. My normal mouthpiece is a Mt. Vernon 1 1/2C, a much larger mouthpiece.

During those 20 minutes, however, the 10 1/2 is a delight, being effortless to play and having a very compact, beautiful sound.

I believe that players who use smaller mouthpieces would love this vintage gem!

Thanks AnthonyinVT. I am happy with my current Bach 10.5C (may be in that era too. Might be interesting to compare against other Bachs at some point.

Winghorn, the description you have it pretty accurate, except it doesn't break down after the 20 minutes for me (at least so far!), but it is not only effortless, also has very crisp articulations, and ease of playing above the staff and getting a very nice tone for legit type stuff too. It may be the Adams A1 that is the other factor making this combo good - not sure. Now for playing with more veiled attacks for jazz, this piece is not right for that, for me at least.

When I began playing lead in the swing band 1968-9 I looked for mouthpieces to help me. First thing I bought was the Vincent Bach Corp 10 1/2 C but having played for some time I bought a Bach 1 1/4 C, together with my new King (1970) - ´cause my dealer told me to do so. And I stayed with the 1 1/4 C finding the 10 1/2 C too "cramped", in comparison bad projection and overall sound.

Today I guess that as the 10 1/2 C has a much smaller diameter (according to the Vincent Bach Mouthpiece manual from 2002), 15,90 mm; is somewhat more shallow, has a smaller cup, I wasn´t able to focus my chops well enough.

The 1 1/4 C felt much more 'free', had (has, I had to borrow one the other day) a magnificient projection. And my comfortable range was up to high E. with optional F F# Gs.

Maybe I should try the 10 1/2 C again?? Lately I haven taken lessons......

I picked up a 1980s Bach Corp. 10 1/2C as an experiment. I wanted to see if I could play it, having heard that Jack Sheldon played a 10 1/2C from the 1960s onward. I really love his sound.

Unfortunately, it didn't work well for me. It felt kinda stuffy, though I liked the diameter.

I then bought an Artisan 10 1/2C, thinking it would open things up a bit due to the larger backbore. Bingo. No more stuffiness.

In my Mt. Vernon Bach mouthpiece brochure, the 10 1/2C is described as “the best all-around mouthpiece”, used in many symphony orchestras and dance bands.

The Mt. Vernon brochure further states that the Bach 1 1/4C is the model played by Vincent Bach himself.

I played a “new old-stock” Mt. Vernon Bach 1 1/4C for many years until my wife inadvertently tossed it out. Luckily, I also had a “new old- stock” Mt. Vernon 1 1/2C. It actually took me several months to get used to its smaller cup diameter, but I have been playing on it ever since.

I currently have fifteen Bach 1 1/2C mouthpieces of every vintage, and twelve Bach 3C mouthpieces of all ages. What can I say? I love Bach mouthpieces!

I'm curious about the 10 1/2 C vs the Olds 3...I have both and am deciding between the two...The 10 1/2C works a little better for me, but the Olds 3 is also good after I warm up with it a little

they seem to have similar-ish shapes:

From that scan, it appears to me that the 10 1/2C would feel slightly larger (rim ID) on the lips.
How would your describe their rim 'feel' - in both playing and non-playing contact?

10 1/2 C seems maybe to feel larger, but not dramatically...when playing definitely easier to get good tone on low notes...with Olds 3 low notes are stuffy at first & only get somewhat better as I warm up

The 10 1/2 shoe size is also amazing! I want to shout it to the rooftops and get some for all my friends and family! Same thing. Glad it’s your size.

I have a 10 1/2C. I love it until my lips swell. Then it shuts down on me, and I have to reach for something larger.
