Bach 42B Stradivarius (Traditional Wrap)

About the Bach 42B Stradivarius (Traditional Wrap)

The 42B's 8.5-inch yellow brass bell and dual-bore slide define what most players think of as the default professional tenor trombone sound - a centered, versatile tone equally at home in orchestral, chamber and solo repertoire. Its traditional-wrap F attachment routes the rotor tubing through the more convoluted path many orchestral players specifically prefer for its familiar resistance and tonal centering over the more modern open-wrap alternative.

Bach's Stradivarius trombone line carries the same design lineage and naming conventions as the company's famous Stradivarius trumpets, and the 42B specifically has become so dominant in American orchestral trombone sections that its bore and bell dimensions function as an unofficial industry reference point - a genuinely rare case of one manufacturer's model effectively defining an entire instrument category's expected sound.

Sound character of the Bach 42B Stradivarius (Traditional Wrap)

The 42B shares its 8.5-inch yellow brass bell with the 42BO, but uses the traditional-wrap F attachment - a more convoluted tubing path that adds a bit more backpressure than the open-wrap 42BO, giving a slightly more compact, focused core to the low register and F-attachment work that many orchestral players prefer for its familiar resistance.
