BachMega Tone Tuba/Sousaphone Mouthpiece 18
Independent shopping perspective
The Korena take
Bach's heavy-blank Mega Tone mouthpiece in size 18, for tuba and sousaphone. For players who want more mass behind the sound.
Strong match
Who this is for
- Tuba players who want a more solid, centered feel
- Sousaphone and tuba players sharing one mouthpiece
- Moving up from a standard-weight Bach piece
Consider the trade-offs
When to look elsewhere
- Players who want quick, light response — the extra mass slows it
- Euphonium or baritone players, who need a smaller shank
- Beginners still building basic tone and endurance
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Bach size 18
Bach numbers run larger as they drop, so 18 is a smaller cup than their 12.
Detail 03
Smaller cup
Easier to control and less air-hungry, which helps endurance on long rehearsals and marching sets.
Detail 04
Tuba/sousaphone shank
Same taper for both, so one piece covers a concert tuba and a marching sousaphone.
Detail 05
$159
Priced above Bach's standard line. The premium is for the heavier blank, not a different size.
Detail 06
Extra weight in hand
Noticeably heavier than a standard mouthpiece. Worth checking it against your case's mouthpiece slot.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is Mega Tone?
Bach's heavier-blank mouthpiece line. Extra mass around the cup gives a firmer, more stable feel compared with their standard-weight pieces.
02How is 18 different from 12?
Bach numbers get larger as the number drops, so 18 is a smaller cup than 12. Easier on endurance, less air moved.
03Does it fit a sousaphone?
Yes. It is made for both tuba and sousaphone, so the same piece works on either horn.
04Is the heavy blank worth the extra money?
It depends on what you want. The mass adds stability and a more solid core, but response is slightly less quick than a standard blank.
