The Bach 42B Stradivarius is a professional tenor trombone with an F attachment that has been a mainstay in symphony orchestras and wind ensembles worldwide for decades. Featuring an 8.5-inch one-piece hand-hammered yellow brass bell and a .547-inch bore, the 42B delivers a rich, powerful sound with excellent depth in the low register and a brilliant, singing quality in the upper range. The open wrap F attachment provides a free-blowing feel with minimal resistance when engaged, ensuring smooth transitions between the Bb and F sides of the instrument. The chrome-plated nickel silver inner slide is fast and responsive, with a fit and finish that promotes effortless legato playing. Build quality is exceptional, with precision-machined components and a clear lacquer finish that allows the brass to vibrate freely. This trombone is the instrument of choice for countless professional orchestral trombonists and serves equally well in jazz big band and studio contexts. It rewards players who have developed strong air support and embouchure control. Individual Bach horns can vary somewhat in playing characteristics, so trying several examples is advisable when purchasing. Players seeking a lighter, more agile instrument for small ensemble jazz may prefer a smaller bore model.
