Valve Conversion Kits

We have received request upon request for our Axial Flow (Thayer) valves. We are now pleased to offer conversion kits that will allow you to modify your existing Bach, Conn, or other trombone of choice with an Edwards valve system. We are too busy building horns to do the conversions ourselves, but we will be happy to refer you to a competent repair tech that can do the work.
