guitar mill necks

There are a large number of physical components that make up a guitar. Some, like chords and scales, are obvious. Others, such as nuts, are less apparent, but are still visible. But some components of the guitar can not be seen at all because they are hidden inside the instrument. This is the case of tensor, a rod metal that runs through the neck of a guitar. This part of the guitar has existed at least since the early 1900s, although it was not patented until 1921. Despite the fact that a tensor can not be seen, is still an essential part of a guitar, one that can add quality and longevity of an instrument.

Ideally the arm of a guitar should have a relief, or bow. This form allows a reasonably low action (more on that later) in high positions and still fingerboard allows the strings to play well in the positions below. A tensor is essential to maintain the relief ideal. As mentioned, the truss rod runs through the guitar's neck. Each rod has a mechanism that allows the rod to be loosened (moved towards the body of the guitar) or tight (moved further up the guitar neck). A stem position can be made to compensate for changes in relief of neck. Such changes may be caused by several factors: changes in humidity, the aging of the wood in the neck or additional strain on the guitar strings. It is this last factor that most often creates the need for the tensor.

Truss rods are not found in acoustic guitars, because they are not required. Nylon strings of such instruments do not require high voltage, which means that the necks of the instruments are not very stressed. Steel strings, on the other hand, require much higher voltage. Because the tension is so high, can actually cause the guitar neck to warp over a period of time, sometimes to a point beyond repair. A tensor helps to counteract this effect by strengthening and stretch the neck.

Tightening a tensor also affect the intonation of a guitar. When the rod is tight, it stretches the neck, which causes guitar strings to move closer to scale. Conversely, when the rod is loose, the neck tilts forward and the strings are away. The distance between the strings of the fingerboard affects the way the instrument operates, or action, "and this is a determining factor in the sound of an instrument.

When a tensor is dual-action "Variety, this means that the rod can be tightened and released. Not all rods in both directions: they can all be tight, but the pattern can only fret be released to some extent, because in most cases, guitar necks need to be stretched, rather than allowing that double. With a dual action truss rod, both tightening and loosening are possible, which means that the neck can be done to double or forward or backward.
