Basics – regulates the sound, control the tilt to not be moved, use graphite in bed of from the strings.
Bridge is one of the most important parts of the instrument. It regulates sound like determines the height and the connection on the strings to the instrument, and is held in place only by the tension of from the strings.
Feet should be well shaped to the contour of the instrument top so that the Bridge standing perfectly upright, and his feet with a good contact on the top. If it is tilted in either direction, the instrument will lose some of their sound and the bridge can be curved or to fall and damage the top of the instrument. Check tilt becomes like watching it from the side. It should be also equally spaced from the inner recesses of F-holes, and at right angles to the back – i.e. side towards tailpiece to top of the instrument. If it is already curved, it is time to be straight or replaced.
If it is necessary to adjust, the position must be done carefully. It is important to do, as this will improve the sound and prevent curves. (It is better to get a personal demonstration by luthier on how to straighten our bridge). Straightening can become with a slightly “pinch” by your thumb and index finger to move it in the required direction. Place a small template to right angle behind the bridge, to check whether straight enough. Often twisted to one side, use the same “pinch” the removal of this twist will also improve its performance.
Bridge often tilted slightly forward by the tension of from the strings when tune, periodic control whether this has happened and strive always to keep it straight. Little graphite in the area of bed on the strings will relieve the contact and will reduce the effect of pulling forward when tune up.
To protect the bridge from damage in the contact of A and E strings used protectors (most often glued leather). In the fall of this leather use plastic tread, which are became with the strings or luthier to change leather. Do not leave the bridge without protector, as this will damage it irreparably.
Each bridge was made to fit at specific location on the instrument. Any change left-right or up-down is undesirable. Typically, this may occur when changing all the strings simultaneously.
If our bridge fall or broke, remove the strings and tailpiece from the instrument, this will keep it by further damages before bringing it to luthier.
