Overview
This King 3BF Silversonic Tenor Trombone, built in the early 1970s, features the classic sterling silver Silversonic bell with gold-washed interior, F-attachment, and original components throughout. The instrument retained original lacquer and included its original King coffin case.
Before sale, it received a full shop service at The Brass Exchange including chemical cleaning, slide inspection, and mechanical adjustment. The handslide operated smoothly and the valve section functioned quietly and reliably.
The King 3B series has long been one of the most widely recognized small-bore tenor designs, and Silversonic models are especially appreciated for their distinctive construction and appearance.
Player Perspective
King 3B-series trombones have been popular choices for jazz ensemble and commercial playing for generations. The 3BF adds an F-attachment while keeping familiar King ergonomics and response.
Sterling silver bells require a bit more energy from the player to fully resonate, but once mastered they can produce remarkable tonal energy that many players appreciate. Clean early-1970s examples like this remain sought after by players looking for a dependable classic King jazz tenor with F-attachment capability.
