Bach 42B Stradivarius Series Trombone

When Vincent Bach founded the Bach Stradivarius Instrument Company circa 1920, he had a vision of creating expertly designed, well constructed instruments of superior quality.That vision is alive today in the embodiment of the Bach 42B trigger trombone.

The 42B is the prototypical large bore, symphonic trombone.It is substantially made while not too heavy.It projects well while allowing for dynamic contrast.The tone of the 42B is dark, rich, and warm.The only common complaint about this trombone is the slide does not slot as well as some of its competitors.
