Overview
This King 3BF tenor trombone from the 1970s features the classic rope-style bell engraving and serial number 471175. It is the traditional small-bore King 3B design with an F-attachment, 8-inch bell, and .508-inch bore nickel-silver handslide. The King 3BF has long been a favorite for jazz ensemble and commercial playing, offering the familiar response of a classic 3B with the added flexibility of an F-attachment.
This instrument was serviced by The Brass Exchange and played properly throughout the range. The slide was straight, quick, and comparable to many of the better King 3B slides we have encountered. There was evidence of earlier repair and solder work completed before the instrument arrived at our shop, and the lacquer showed wear and loss consistent with its age. Although not a cosmetically pristine example, it was structurally solid and played very well.
For a high-school or college player working within a budget, this King 3BF offered a practical and musical jazz tenor with an F-attachment. Its value was found in its sound, response, and slide performance rather than cosmetic perfection.
The original coffin-style King case was included in fair condition.
