I am happy to announce the latest advancement in the 5MM Modular Mouthpiece System. The "Compression Throat" designs outlined below will definitely improve clarity, attack and stability in the upper register for everyone.

Compression Series Throats offer more front end to the attack. Great for lead or situations where the attack is more important.

"C" series - bright and loud with a balance of depth and ease in upper register
"E" series - extremely bright and loud, easiest in upper register
"H" series - aids in upper register while remaining big and full

This 1-minute video gives you a taste of what is possible with Compression!

Understanding the numbers

Example 1:
B-120-20 designates the smallest diameter of .120" and an end diameter of .200" (matches Cup B, this is a small throat suitable for lead work)

Example 2:
F-145-21 designates the smallest diameter of .145" and an end diameter of .210" (matches Cup F, this is a medium throat suitable for all around playing)

Example 3:
H-170-22 designates the smallest diameter of .170" and an end diameter of .220" (matches Cup H, this is a large throat suitable for ballads and Mahler's 5th symphony)

We recommend experimenting with throats of various sizes to achieve your desired tone color for each performing situation. Smaller diameter values produce a more focused tone while medium sizes offer vibrancy and warmth and large throats minimize projection producing a pleasant cello-like velvet tone. You may experiment with any diameter variations listed as they are all regular stock items. Change Throat sizes in seconds and see for yourself how this one factor will help you fine tune air flow, color, projection and intonation.

Throat "length" should match the Cup "depth" value
Throat "exit diameter" should match the Backbore "initial diameter"

How does the 5MM Modular Mouthpiece system work?

Why do I need it if I already like my mouthpiece?

I have a drawer full of mouthpieces and I don't need another one, do I?

The answers to all of these questions are revealed in the video below. My comprehensive "5MM Owner's Manual" video walks you through how the 5MM System works while highlighting benefits not found in any other system.

Maybe it's time to list your mouthpiece collection on Craigslist or eBay and embrace the modern solutions available today. Yes, your Mt. Vernon 3C is a great mouthpiece, but could it be better? Could it be more versatile? Could it reliably do things it currently doesn't? Nope, but our 5MM version does more than you would believe. Sound too good to be true? Watching this video could change your mind, so those of you not interested in more mouthpieces should really hit the back button right now...
