Archive Overview
This Bach LT42A Stradivarius tenor trombone, serial number 225905 and built within the past few years, 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.
As of 2025, new Bach LT42A Hagmann models retail well above $5,500, making clean pre-owned examples an appealing option for advancing players seeking a professional-level instrument.
This instrument included a brown Protec Pro-Pac case.
✦ Historical Perspective
The Bach 42A Hagmann model reflects the evolution of Bach’s classic 42 large-bore tenor trombone into a more modern, free-blowing orchestral instrument. The open-wrap Hagmann valve reduces resistance in the low register compared with traditional closed-wrap rotors, creating smoother transitions and even response.
Gold brass bells, with their higher copper content, provide a warmer tonal core than yellow brass while retaining clarity and projection. This tonal flexibility has made gold-brass 42-series trombones popular with advancing students, college players, and professionals alike.
The Bach 42 lineage remains one of the most recognized large-bore tenor trombone families ever produced. Archive listings like this one help players compare build eras, specifications, and tonal characteristics across decades of Bach production.
