A Bach Signature: The "Stradivarius" Standard for Brass
The history of Bach mouthpieces begins with Vincent Bach, musician and engineer, who started production in 1918 in New York to meet a simple need: to find a reliable and high-quality mouthpiece. This manufacturing standard later extended to instruments (trumpets from 1924, then trombones in 1928), to the point that musicians associated Bach with an absolute reference, hence the name "Bach Stradivarius." Even today, Bach mouthpieces remain a safe choice for building a consistent sound and controlled response.
For Which Musician and Usage?
This Bach mouthpiece is suitable both for beginner musicians seeking a stable and easy-to-control model, and for intermediate to advanced players wanting a homogeneous response in rehearsal, wind orchestra, brass band, pop, or more classical repertoire. Its semi-deep cup makes it a versatile option, comfortable when alternating between projection and warmth.
Sound and Design
With its semi-deep cup, the mouthpiece promotes a balanced timbre: enough body to support dynamics while maintaining precision in attack. The 6.63 mm throat contributes to good airflow and a smooth playing sensation, while the small bore format helps maintain ease of emission and direct response. The silver-plated finish provides a comfortable touch and a clean feel on the lips.
