The Bach Stradivarius 50B is a professional-level single rotor bass trombone built for players who demand a rich, resonant tone and solid low-end support. This horn features a traditional rotor valve in F, providing access to extended low range and alternate positions while maintaining a familiar playing feel.

With a .562″ large bore and a 9.5″ one-piece hand-hammered yellow brass bell, the 50B delivers a warm, broad tone that blends beautifully in orchestral sections and still has the power to cut through in solo or ensemble passages. The inner slide offers smooth action, while the yellow brass outer slide contributes warmth and tonal complexity.

This example shows notable lacquer wear consistent with use, but remains fully functional with no mechanical issues. The slide action is responsive, and the valve operates smoothly.
