The BACH Stradivarius 42B Tenor Trombone is a benchmark instrument made in the USA. With its large 'L' bore of .547 inch (13.90 mm) and an 8.5 inch (216.00 mm) yellow brass bell, it delivers a magnificent sound, appreciated by orchestras, soloists, and chamber music ensembles. The nickel-silver slide provides smooth action, while the original VINCENT BACH 6 1/2A mouthpiece allows for great flexibility and precise response. The instrument comes with a Deluxe 1864 wooden case.

The nickel-silver inner slides and brass outer slides ensure increased durability and precision. The lacquer finish on the trombone gives it an aesthetic appeal. The 42B is distinguished by its extraordinary sound projection, allowing it to shine in various musical situations.

Although the build quality has improved, some aspects remain perfectible. Some musicians criticize the case provided with the instrument, finding it impractical and outdated. Furthermore, some feel that the 42B can constrain play, requiring more advanced technical mastery.

Despite these considerations, the BACH Stradivarius 42B Tenor Trombone remains a preferred choice for demanding musicians. Its exceptional sound and versatility allow it to excel in a variety of musical contexts, making it a trusted instrument for both professionals and passionate amateurs.
