This Bach Stradivarius 42BO is a professional large bore tenor trombone with the same core technical specifications as a standard brass 42BO: an 8.5" one-piece hand-hammered yellow brass bell, standard-weight yellow brass handslide, and a .547" bore for large shank mouthpieces (one included). Beneath the silver plate, every dimension matches the traditional brass model — the difference is in the finish. Is a single owner horn only used for a couple of years- and made within the last decade.
Trumpet players discovered the advantages of silver-plated instruments over a century ago, back when lacquer finishes were heavy and short-lived. The old-style lacquer behaved more like paint, wearing away quickly and sometimes flaking after only a few years. Silver plating was the answer — not only more durable, but it also made instruments livelier and more responsive. While silver does require extra care, such as frequent wipe-downs with a polish cloth or the occasional full silver polish, many players don’t mind a little tarnish at all.
In 2025, a brand new Bach 42BO in silver plate is available only by special order from Bach dealers, with a price tag of over $4,400. This example offers the same playing experience and appearance at a far better value — and it’s in stock for immediate delivery.
The 42BO’s open wrap F-attachment keeps airflow free and smooth in the lower register, improving legato response and lowering resistance.

Common Questions About This Instrument
Q: How does silver plating affect the sound compared to lacquer?
A: Silver plating can add a touch of brilliance and crispness to the sound while still maintaining warmth. Many players find silver-plated instruments have a livelier response and a slightly more focused projection.
Q: Why doesn’t Bach offer more silver-plated trombones?
A: We don’t know exactly — Bach has traditionally kept silver plate as a special-order or limited-availability finish. It’s more common on their trumpets than trombones, making this example a rare find.
Q: Is this horn suitable for professional orchestra work?
A: Absolutely. The Bach 42BO is a long-standing standard among orchestral trombonists. Its large bore, 8.5" bell, and open wrap rotor produce a broad, commanding tone that blends well in section playing but can also project as a solo voice.
