The innovation of the patented "Infinity" valve comes to the Bach line of bass trombones. A newly designed bell section utilizes a dual valve, independent system featuring open response, balanced action and minimal maintenance.
The newly designed Bach 50AF3 bass trombone utilizes the patented "Infinity" valve in a dual rotor, independent configuration. This model offers the open feel of an axial-flow system, but eliminates the metal to metal contact found on other axial-flow designs.
