Vincent Bach Mouthpiece Tuba and Sousaphone Mega Tone Series K335 Model 7

I'm currently using this mouthpiece on a 5 valve CC tuba. It produces a dark powerful sound. It does take some practice to get used to the wide opening and the wide throat. Once you have mastered your breathing with this mouthpiece you will be amazed at the deep, poweful tone it produces. I'm still working on the higher registers to produce a consistent tone, but It is getting better with each practice.

when I started playing with this mouthpiece not only did it improve my tone, but it expanded my range to more than 4 octaves. As a high school level musician this is above and beyond what I expected myself to be capable of and am very happy with the quality product Vincent Bach has produced.

I like it

The cup of this mouthpiece is just the right width for my, admittedly, fat lips. Not to mention the added mass from this mouthpiece really brings out the warm sound the tuba has. I love this mouthpiece.

This is the mouthpiece I've been looking for. I increases tone, makes articulation easyer, it increases volume and overall quality of sound.
