Bach 7, 9, 11, 12

[Rusty]

There was a couple of interesting posts on TTF that have disappeared on the ‘no C’ Bach mouthpieces.

Just wondering if anyone uses or has had much success on these mouthpieces?

I have a couple of 11s...a recent one that’s very deep with a very tight throat (feels pretty stuffy), and one from the late 1960s that’s not as deep with a more open throat that plays great and I quite like. Not as bright or as much zing as a good 11c, but feels like a better all round piece with a great fat core and weight to it.

I also played a Bach 9 for a number of years...very mellow, but pretty hard work playing lead

I have a New York 7, a modern 5, and a Corp 3. I like them a lot. The older mouthpieces sound really great, but the 5 is the goldilocks for me in the middle for small horns. The 3 is perfect in a .525.

I played a Mt Vernon Bach 9 for a long time and loved how it felt and recorded, especially while improvising, but it wasn't snappy enough for lead playing and pop. Greg Black copied my Mt Vernon 9 rim and NY 11C cup, making one piece, and although I used it for a while, the ratios ultimately didn't work for me.

I use a Mt Vernon 5 with my medium bore, I really like that piece.

I've owned and played a variety of 7s as well. Like those, but feel for some reason the throat seems to be the smallest of the un-lettered Bachs and can be fickle for me.

FWIW I'm pretty sure Conrad Herwig has played an old 11 for a long time and he has the most beautiful buzz I have ever heard.

I use a MV 11 in my small trombone. Does the job.

I have a MV 12C that feels more like a modern 11C. Twenty years ago I used that mouthpiece a lot, but the loss of plating has made me search in another direction. Modern 11C's are great too but... No mouthpiece beats my 6 3/4C.

The 7C is good, but for some reason not the best for me at the moment. I think it is the edge of the rim that makes it uncomfortable. The same feeling I get with a modern 12C. The contour of the 6 3/4C and 11C rims must be closer to the Hammond mouthpiece series I'm used to with my larger trombones.

I have never played a 9.

I played on a 9 for a while and liked it. I still use it on my .500 bore horn but playing larger on the .525. Its a good piece. Bigger than most people think it is.

What makes these different from the "c" mouthpieces?

[BGuttman]

Bach describes the cup depths with numbers. A is the deepest, B (or sometimes no letter) is a little shallower, then C, D, and E are shallower still. This nomenclature was used for the small shank mouthpieces. I don't know of a single A mouthpiece; 6 1/2 AL was actually a custom mouthpiece and not an A cup.

The B (or unlettered) cups were intended for the American Baritone of the day. They were intended to be a little deep for trombone. The C versions were intended for trombone, with D and E for special cases where you needed to emphasize the upper register.

So how are they different without the letter?

An unlettered cup is also the B cup and is deeper than the more common C cup.
