Pre-Owned Bach 42BO Professional Tenor Trombone - Open Wrap, Clear Lacquer (Near Mint)
For sale is one the champions of the trombone world: a Pre-Owned Bach 42BO Professional Tenor Trombone. Vincent Bach large-bore trombones have defined the American orchestral sound for generations. When collegiate professors and principal trombonists recommend an instrument, the Bach 42 is almost universally at the top of the list.
What makes this specific horn such an incredible find is its condition. It comes to us completely original and in near-mint, "like new" shape. The clear lacquer is glowing, and most importantly, the rotor valve is exceptionally tight. If you are looking for a pristine, lifetime-quality professional trombone without paying the brand-new retail premium, this is your horn.
This is a great instrument the serious collegiate music major, dedicated conservatory student, or gigging orchestral professional. The large .547" bore requires a mature volume of air, but it rewards the player with a massive, warm, and room-filling symphonic tone that blends perfectly in a section.
- Open-Wrap F Attachment: The "O" designates an open-wrap tubing design for the F-attachment. This removes the tight bends found in traditional wraps, offering drastically less blowing resistance and a much more open, free-blowing low register.
- The 42 Bell: The legendary 8.5-inch, one-piece hand-hammered yellow brass bell provides a rich, broad, and highly colorful tonal core with unmatched projection.
- Large Bore (.547"): The standard size for professional symphony work, allowing for maximum resonance and dynamic flexibility.
