King 4B Sonorous F Attachment Trombone Background:

A large bore Trombone with a big bell that is capable of great volume in all ranges.  The Trombone with an extremely resonant low register.  An excellent instrument for the large symphonic band or orchestra ensemble. Adding the F Attachment to the King 4B has increased its technical potential and extended its range without changing its distinctive basic sound.  The bore of the F Attachment “matches” the .547 bore of the slide section thereby preserving its clear sound down to its lowest register.  Rapid valve action and a long pull to “flat” E are of course, part of the  F Attachment’s design and construction.
