Bach Stradivarius LT42BG Tenor Trombone Overview
The Bach Stradivarius LT42BG is a professional Bb/F tenor trombone built around a .547 large bore and an 8 1/2 inch one-piece hand-hammered gold brass bell, paired with a traditional closed-wrap F-attachment for the classic symphonic feel and response. This is an open box instrument from a large dealer purchase of King, Conn, and Bach Stradivarius trombones, offering the same core build and playing characteristics players expect from the 42-series while providing meaningful savings versus standard new-in-box pricing.

Who the LT42BG Tenor Trombone Is For
The Bach Stradivarius LT42BG is a professional large-bore Bb/F tenor trombone designed for symphonic, orchestral, and advanced ensemble playing where clarity, projection, and a traditional blow are priorities. The 8 1/2 inch hand-hammered gold brass bell supports a warm, centered tonal core, while the .547 bore and closed-wrap F-attachment provide the resistance profile many orchestral players prefer for articulation control and stability across the range.
Within the Bach lineup, the LT42BG is a long-standing reference model for “classic” symphonic tenor trombone sound and response, with the gold brass bell adding a subtly warmer color than yellow brass while retaining definition. The lightweight nickel silver slide construction and chrome-plated inner tubes are specified for smooth, fast slide action in technical passages and consistent feel across positions.
Common Questions About The Bach Stradivarius LT42BG
Is the Bach LT42BG suitable for professional orchestral use?
Yes. The LT42BG is a .547 large-bore Bb/F tenor trombone with an 8 1/2 inch hand-hammered gold brass bell and a traditional closed-wrap F-attachment, a configuration commonly used for professional symphonic and orchestral repertoire.
What does “closed wrap” mean on this F-attachment?
Closed wrap refers to the more compact routing of the F-attachment tubing around the valve section. Compared with more open layouts, it typically preserves a familiar resistance and feel that many players associate with traditional symphonic tenor trombone response.
What should I expect from an “open box” Bach Stradivarius trombone?
This instrument is sold as open box and is guaranteed to play like new and look great as shown. It has also been professionally serviced, set up, and play-tested to verify slide smoothness, valve operation, and overall function.
