Vincent Bach combined his unique talents as both a musician and an engineer to create brass instruments of unequalled tonal quality. Often copied but never duplicated, Bach Stradivarius instruments today remain the sound choice of artists worldwide. The Bach B188 features our antimicrobial lacquer to give this instrument a natural barrier to bateria and deactivates viruses.


  • Initially designed as an alternative to the valve trombone, the B188 bass trumpet is well suited for everything from Wagner operas and solo work to jazz ensembles, brass quartets, and marching bands.
