Vincent Bach: Craftsmanship Excellence Turned into a Benchmark
Since 1918, Vincent Bach has upheld a simple vision: a mouthpiece must offer reliability, consistency, and true sonic coherence. The Symphonic series follows this tradition, designed for musicians seeking broad projection and a deeper color while maintaining familiar playing references.
For Which Trumpeter?
This Bach Symphonic 1 1/2C is aimed at intermediate to professional trumpeters who want a stable response and solid sound presence in orchestra, wind ensemble, or classical repertoire. It is also well suited for contexts where a round and homogeneous sound is preferred over a very bright brilliance.
Sound and Design
The cup (internal shape influencing attack and tone) in 1 1/2C remains close to classic Bach sensations, while the throat (narrow passage) and backbore (rear part) in version 24 promote a more "open" feel. The result: comfortable response, wider projection, and a naturally darker timbre, ideal for symphonic playing. The silver-plated finish provides a crisp feel on contact and good grip.
Recommended Compatible Accessories
For daily maintenance, a mouthpiece brush and a protective pouch (universal mouthpiece size) are reliable choices to limit oxidation and maintain hygiene.
