A Reference Born from Bach's High Standards
Since 1918, Vincent Bach has applied the rigor of a musician and the precision of an engineer to mouthpiece manufacturing. The Bach Stradivarius brand has established itself as a key name in brass instruments, and its mouthpieces remain a reliable choice today for gaining stability, comfort, and consistency in playing.
For Which Musicians and Styles?
This mouthpiece is intended for trombonists and large bore brass players, from serious beginners to professionals. It is particularly suitable for contexts where easy sound production and clear articulation are sought: orchestra, wind band, brass band, popular music, or more classical repertoire.
Sound and Design
With its medium-deep cup (25.40 mm diameter) and a medium rim with a soft outer edge, it promotes good centering and lasting comfort. The 0.261 throat helps achieve efficient airflow, contributing to a lively response, more immediate attack, and even projection across all registers.
