This King 3B Silversonic from the late 1950s is one of the earliest examples we’ve seen at The Brass Exchange since opening our doors. A true H.N. White–era classic, this horn has remained in the same family for decades, carefully maintained and lovingly passed from father to son.
All parts and lacquer are original, with natural cosmetic wear in the bell section and outer slide that only adds character without affecting performance. The handslide has had a full professional setup and plays beautifully. As many brass enthusiasts know, when good players take care of their horns, they generally play well—but when great players maintain them, the result can be extraordinary. This is one of those rare instruments.
The 3B Silversonic is renowned for its brilliant tone and projection, thanks to its sterling silver bell flare combined with King’s signature craftsmanship. The current 3B models being produced today are essentially replicas of these late 1950s horns—but this one is the real thing, built during the golden age of the H.N. White company.
Included with this instrument is a brand-new Protec Max hard shell case and mouthpiece. For players seeking the finest possible example of a vintage King 3B Silversonic, this instrument delivers both historical authenticity and outstanding playability.
