B4L S1

B4L S1 - Classic Resonance LT & Prana Resonance LT


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


For many years the B4L S1 (along with the slightly deeper version called B4LD 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 B4L S1 replaced the original B4L in the mid 2000s. This combination of fairly large rim size with a shallow lead cup makes for a wide but bright lead trumpet sound.



The B4L S1 is made in the lightweight Resonance LT body.


Plating & Finish:

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

Prana Resonance mouthpieces have a brushed 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.
