Unity B4LD

Unity Mouthpieces: the latest generation of Monette mouthpieces


Size Comparison: Monette B4LD S1 (aka B4LDS), conventional 1-1/2 or 2 rim and Bach 'D' or Schilke 'B' cup depth


Another very popular size, this 'LD' cup is a 'deepened lead' mouthpiece. It is an extremely popular choice for commercial playing, broadway shows, and other applications where lead playing is mixed with more classical playing styles. The B4LD size and depth offers great versatility. Most players who use larger Monette mouthpieces as their main size find it seamless to switch to the B4LD for lead or commercial playing.


*If you have never used our B4L/B4LD rim before, we would first recommend the Unity DM-4LD with its newer '-7' rim design. But players who want the familiarity of the original B4L rim will love this Unity version of the B4LD.



The Unity B4LD 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.
