King 4B Legend Professional Bb/F Tenor Trombone – .547″ Bore, 8″ Bronze Brass Bell, Traditional Wrap F attachment, Standard Rotor, King Hard Case and Genuine King Mouthpiece – Lacquered Finish
The King 4BF trombone has a classic large bore symphonic trombone design, with the advantage of having an F-attachment trigger to extend the range of the instrument and help with those difficult “extended arm” passages. This model features a .547 bore and a bronze brass bell to offer the performer a quick response with a warm, full tone.
