Hello,

I was asked a question by a prominent player today concerning Bach backbores and his lack of knowledge of the Bach backbore numbering system.

He is new to the “threaded” backbore concept and has always played the backbore that the Bach factory suggested and had sent with the rim/cup of his choice.

I have my opinions on the subject, but I told him I would ask my esteemed colleges on the TM site to either validate or “tear apart “my long held concepts.

He told me he went to the Selmer site and said " Well, a # 24 comes with an A cup, which is described as bigger (than what?), darker (than what?) symphonic and a V cup comes with a # 25 which also list " big " as a description along with a 87 ( big, free blowing ) so what gives"

Simply list biggest to smallest:

24
7
3
117
87
76
41
57
25

Plus any others not listed.

If you can give a personal description after the backbore number, so much the better and I will forward every and all determinations to him. He asked I didn’t reveal his name, but it’s an older “household one “and you would be surprise how little some top named players know about the gear they use.

Note to Bach Trumpet Moderators;

I asked this question in the “ Bach Trumpet “ forum because I hope it would get more viewings and more diverse opinions then in the “ All - Encompassing “ mouthpiece forum, but if you feel it belongs in the mouthpiece section , I’ll understand if it gets moved.
