Trombón de Varas con Transpositor Sib/Fa Bach LT42A Stradivarius Lacado

This Bach LT42A Stradivarius tenor trombon represents a modern example of Bach’s long-standing 42A large-bore tenor design. The instrument featured an 8.5″ one-piece gold brass bell, lightweight nickel-silver LT .547 slide, and open-wrap Hagmann F-attachment valve, a configuration widely favored by orchestral players seeking warmth with responsive articulation.

The trombone was in excellent structural condition with only minor cosmetic lacquer loss near the upper valve port and slide end crook, likely from normal handling or factory finish variation. Our shop performed a full inspection and setup, including slide wash, inner-tube polish, and mechanical check. The slide action was smooth and quiet, and the Hagmann valve aligned properly with quick response.

Pairing a gold brass bell with a lightweight nickel-silver slide is a time-tested orchestral setup, offering warmth and tonal depth without sacrificing clarity. Many professional players favor similar configurations for symphonic and chamber literature because they blend easily in section work while still projecting when needed.
