B4LD S1:

Classic Resonance LT & Prana Resonance LT (lightweight)

Classic Resonance & Prana Resonance (standard-weight)


Size Comparison: Conventional 1-1/2 or 2 rim size with D cup depth


For many years the B4LD S1 (along with the slightly shallower B4L S1) has been the go-to lead mouthpiece size for players who prefer a B4 (1-1/2C equivalent) rim size or larger. With its improved 'Slap' cup contour, the B4LD S1 replaced the original B4LD in the mid 2000s. This combination of fairly large rim size with a semi-shallow cup makes for an extremely versatile mouthpiece. It works very well for lead players who don't like small/shallow cups, and it can function as the perfect compromise between a standard-depth cup and a shallow lead cup. Very popular with Broadway show players, big band section players, and players who want one mouthpiece that they can use for both lead playing and non-lead playing.



The B4LD S1 is most commonly made in the lightweight Resonance LT body. It can also be made in the standard-weight Resonance body, for players who prefer some extra stability, and a thicker sound with a bit less brightness.

Classic Resonance mouthpieces have a shiny, buffed 24k gold finish

  • 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.
