Unity DM-4LD

Unity Mouthpieces: the latest generation of Monette mouthpieces


Size Comparison: Monette B4LD & B4LD S1, conventional 1-1/2 or 2 rim size, Bach 'D' cup depth or Schilke 'B' cup depth


Dave Monette wanted a new lead trumpet mouthpiece design that would be ideal for players with medium large to large lips, or who simply prefer a fairly large size for lead playing… players who want a mouthpiece to help in the upper register without worrying about bottoming out in cup depth. This includes many players who use our B2-7 and B1-7 size mouthpieces for all-around playing. But that’s not all… he wanted a mouthpiece that provided such an easy upper register with such a rich and centered low register that it could be used in most any musical situation. And the best part of all this is the extreme comfort of the all-new rim contour!


Dave designed the rim for himself… to be the most comfortable trumpet mouthpiece rim he had ever felt. From the first notes, Dave said it was his favorite all-time rim contour. All of our co-workers and closest shop friends were equally impressed with how comfortable this rim feels. Now months after playing the first notes on this mouthpiece, Dave and the others in our shop still say that they love the feel… they say it almost feels like there is nothing on their lips as they play!


The DM-4L & DM-4LD are similar in cup design and depth. They both offer plenty of room in the cup, but the DM-4L is for players who want a bit brighter sound. It’s an ideal upgrade for B4L S1 players who want just a little more depth and depth of sound while still feeling and sounding like they are playing a lead mouthpiece. The DM-4LD is just slightly deeper— it fills out the sound and stabilizes the response just a bit more than the DM-4L. This makes it ideal for players with large or extra large lips and those who want help in the upper register with even more depth of sound and stability of response.



The Unity DM-4LD is usually made in the lightweight Unity body. It can also be made in the extra-lightweight Unity body for players who prefer an even brighter sound. 


Plating & Finish:

Unity mouthpieces can be plated in 24k brushed gold or bright silver.

  • Monette mouthpieces are made-to-order and usually will not be available as ready-made stock. The standard estimated wait time to have a trumpet mouthpiece made is approximately 6-8 weeks. Unity mouthpieces for Bb and C trumpet are often available within a shorter wait time. Uncommon sizes can involve a longer wait time. The exact wait time is unpredictable, as it is affected by many variables. We cannot guarantee an exact completion date or shipping date in advance. Thank you very much for your patience while you are waiting for your mouthpiece to be made for you.
