Bass trombone with top independent valve system.
Getzen Bass Trombones
The special design of the valve system allows the player to access the second (Gb) rotor without playing through the F. This allows the player several ways to simplify slide positions in the low range. The three interchangeable mouthpipes give the player the added advantage of being able to tailor the response of the instrument from the large bore tenor feel of the number one pipe, to the blending characteristics of two , to the wide open sound of the number three. All of these features are amplified by an amazingly efficient, dual gauge bell which is both powerful and beautiful sounding in all registers.
