Having a properly set up bridge on your upright is an important factor in the playability, sound and the long-term health of your instrument.
Here are some things every upright player should know:
The internal, not external, notches you see on the F-holes determine the proper distance of the bridge from the fingerboard. They should correspond, more or less, to the center of each bridge foot. Furthermore the feet should be in a straight line from E side to G side. Bridges without height adjusters won’t generally have issues in this regard, but the feet of bridges with adjusters can become massively askew.
