King Duo Gravis Double Valve Trombone Background:
It’s the heart of King’s superiority. The fastest and smoothest action of them all!
The main purpose of adding an “E” valve to the “F-Attachment has been to make possible a complete chromatic scale without having to retune the instrument in order to play “low-B.”
The new King double valve bass trombone does this in a simple, easy-maneuverable manner which is unique.
Plus offering exclusive features such as: an optional “D” crook making possible to scale down to the lowest “B” without ever reaching as far a 6
th
position, fast and quiet short stroke valve action, and Matching Bore throughout the entire horn.
