The Bach 42AF is the newest and most exciting development in Bach Stradivarius professional trombones. It features the new “Infinity” axial flow valve. This patented valve design eliminates the metal-to-metal contact found in any other axial flow design through the use of sealed bearings both in the nose and in the back plate. This assures tight tolerances that will resist wear over time. The Bach Stradivarius 42AF professional trombone is ideal for both symphonic and solo performance.
