Overview
This Bach 42BO Professional Open Wrap tenor trombone is a strong example of one of the most widely used large bore orchestral trombones in the modern era.
Serial number 212152, this instrument comes from a single owner and has been well cared for throughout its life. It remains in excellent playing condition, with a particularly strong handslide and responsive valve section.
The 42BO features the classic Bach open wrap design, offering a more open feel when the valve is engaged and a balanced response across all registers.
Player Perspective
From a playing standpoint, this horn delivers the familiar Bach 42 core—broad, centered, and stable—with a smooth transition through the valve register.
This particular instrument has been de-lacquered by the previous owner. Many experienced players prefer this finish, as removing lacquer can result in a more immediate response and a slightly more resonant feel.
Combined with a clean, well-aligned slide and a properly functioning valve section, this horn plays freely and would be a solid choice for an advancing player stepping into a first professional-level large bore trombone.
