Vincent Bach: The "Stradivarius" Standard for Brass
Born from the experience of Vincent Bach, musician and engineer, the brand established itself early in the 20th century as a benchmark for brass mouthpieces. After initial productions in New York (starting in 1918), followed by the arrival of Bach trumpets and trombones, the manufacturing standards forged the "Bach Stradivarius" reputation: a sought-after signature for its consistency, machining quality, and reliability from one piece to another.
For Which Musician and Repertoire
This mouthpiece is aimed at the trombonist (from intermediate to professional level) seeking stable playing and a broad sound. Its deep cup and large bore are very well suited for classical, orchestral, wind ensemble settings, and sections requiring sonic density, while remaining relevant in jazz for a fuller, less bright tone.
Sound and Design
With a deep cup and a medium-thickness rim, the response remains comfortable and secure, while promoting a warm and homogeneous sound. The tip diameter of 0.276 inch helps achieve good air reserve, generous projection, and solid foundation in the low register. The 429 backbore (internal profile) contributes to balancing sound breadth and ease of response depending on the instrument and player.
Recommended Compatible Accessories
To preserve the finish and hygiene, prioritize a mouthpiece brush and a brass instrument cleaning spray (universally compatible with metal mouthpieces).
