Perantucci Tuba Mouthpiece PT-50+

I ordered this mouthpiece after moving from an Eb Bass to a Bb Bass and realizing that I was struggling to move as much air as the instrument needed.
After about a year of use now the mouthpiece is still in very good condition, the only make on it being where I dropped it about a foot onto the floor (what can I say, I'm a bit clumsy).
I have found this to be a very responsive mouthpiece that is allowing me great flexibility and a surprisingly decent upper range, whilst still enabling me to produce a lovely rounded sound.
For the price it is excellent.

This mounthpiece is a best-seller, very comfortable with amazing sound, but was not too good for a small tuba (3/4), when used with over 4/4 and pistons was amazing.
