Thayer valve.
The Bach 42T Stradivarius Trombone with Thayer Valve F Attachment has a more open feel from other trombones. The Bach 42T Thayer valve eliminates restriction from the open wrap tubing of the F attachment.
For many years, professional players have added Thayer valves to their instruments at local instrument repair shops at great expense. Now you can buy these magnificent horns with the Thayer valve already installed by the factory and get more value for your dollar.
