Butler Carbon Mouthpipe Shires for Large Bore 5475C

This is a mouthpiece made by Butler, a company that creates carbon fiber wind instrument accessories.

This is a short type for Shires tenor bass trombone.
It produces a calm, warm tone, but I am selling it because it was slightly different from my preference.

For tenor bass trombone.
I used it on a Q Alessi.
There can be individual differences, so if it is too tight, please ask a musical instrument store.
