Can anyone tell me what the difference is other than the V vs C cup?

As far as I am aware, the size 10 trombone mouthpiece is a 10CS not a 10BS so the cup would be shallower.

Per manufacturer's decriptions:

• 10CS: Cup I.D. 25.00mm; shallow V-shapedcup; 6.24mm Throat; Medium backbore; designed by Denis Wick for alto trombone.

• 9BS: Cup I.D., 25.00mm; medium V-type cup, 6.66mm Throat; V-type backbore; for medium-bore trombone; also great alto tbone mouthpiece. Used by Ian Bousfield for alto work.

For what that's worth.

Current production size of the 10cs is 25.2mm, and apart from the cup depth being shallower to me the backbore felt more open than the 9bs.


If they are the original/ older versions the rim shape is different to the modern ones also.
