King 3B Silversonic Trombone – Late 1970s – SN 669226
This vintage King 3B Silversonic is one of the finest examples we've had at The Brass Exchange. It features the classic 8" sterling silver bell, a .508 bore nickel silver slide, and yellow brass end crook. All original parts and lacquer. It has just received full professional shop service including chemical bath, dent removal, and a slide setup. The slide action is superb—responsive, fast, and drag-free.
We’ve had well over 100 King Silversonics come through our shop, and this 3B is among the best. It reflects the high craftsmanship and thoughtful material choices of its time—something players and collectors value. The sterling silver bell, denser than brass, not only shapes the core and feel of the sound, but also absorbs and redistributes energy to deliver a tone that is rich, centered, and full of color. This makes a noticeable difference for both player and listener.
Compared to modern replicas, this horn speaks with the classic voice made famous by players like J.J. Johnson. It’s not just about nostalgia—it’s about that unmistakable character and presence that only a well-aged original can deliver.
Includes original coffin-style case in great condition. This is a prime choice for a jazz player or advancing student ready to grow into a professional horn.
You’ll see similar models listed for more elsewhere, but this one is correctly priced at $2790. A new King 3B Legend Silversonic sells for over $4700 today—and doesn’t include a gold-plated inner bell.
In stock and available for immediate delivery.
