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.

Took up BBb bass last year after playing euphonium. Have tried and wasted quite bit of money finding the right mouthpiece. Can't be bothered with all that gobbledygook about "characteristics" so suffice to say that this is a well made, comfortable heavy mouthpiece that i shall be playing my Besson Sovereign with from now on.

Just loving this mouthpiece. Great low end respone. I can use this for Eb flat as well as Bb Flat. This is my fifth Perantucci so i do like them, alot.

I use this with a Besson Sovereign large bell EEb tuba. It's a large funnel-type mouthpiece (bigger than 24AW), which needs plenty of air, but it gives a warm rich sound. The rim is comfortable, so I don't get so tired after a couple of hours playing. I use it most of the time. It works for me.

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.

Excellent mouthpiece delighted with the sound it creates, very comfortable to play and allows for a very wide range of playing. Especially the lower end notes, highly recommended!
