For bass trombone, I have a DE setup with a MB 109 Rim, an MB J Cup, and an M9 Shank (Morse taper).

The J Cup (~1½G size) is fine, but the other components are just a bit large for my playing.

So (If I've got the correct designations) I'm in search of:

• MB 108 Rim

• J8 Shank (standard Morse taper)

If you have either of these you're willing to part with, please let me know via PM.

Thanks.
