Valve Alignment
Mouthpiece Alterations
General Repairs


The first step in the valve alignment process is to measure your horn to see how far the valves are out of alignment. We use a proprietary measuring system that includes tools designed by Bob and port prioritizing that ensures the optimal playability and evenness of your horn.

You will receive a card that will show the up and down stroke measurements of your horn before the alignment.

In this example, Al's Bach was out by a considerable amount. All of the valves in the upstroke position were positioned too low, as notated by the negative numbers. The first and third valve downstrokes were too high, notated by positive numbers, while the second valve was too low.
