Best Answer

It's a long rod lodged up in the neck of a guitar used for keeping the neck of the guitar straight.

The truss rod is used to allow the neck to bend either way in response to the tension of the strings. Without it, there would be no steel string Guitars, the neck wouldn't be able to handle the tension of the strings. Many beginners think that adjusting the truss rod will lower the "action" or how high the strings are from the fret board of the guitar. This is not entirely true and it is probably more of a Nut and saddle/bridge adjustment that is needed.

Can we install a truss rod to a guitar neck which originally doesn't have a truss rod?

In short you can do, but it's a very lengthly process and will cost you a fair bit of cash. Usually the way to do it (assuming your neck is deep enough to accommodate the truss rod) is to remove the fretboard, then route a channel down the centre of the neck under the board, install the rod with the adjustment nut at the headstock end, then reglue the fretboard. Though TRUSS me, it's a lot harder than I made it sound just then! I'd recommend taking it to your local repair place to get a quote and don't try it yourself unless you're a master router. If the problem you're trying to fix with a truss rod is that you're guitar neck is slightly warped, then a slightly easier option would be to get the frets out, plane/sand the fretboard level and then get it re-fretted.


What is the truss rod in a guitar?

A guitar's truss rod is a long metal rod that runs from the body of the guitar along the back of the guitar's neck all the way to the headstock. It's purpose is to provide strength to the guitar neck against the extreme tension of all the guitar strings. Also, without the stability provided by truss rods, guitar necks would have to be made from much harder and stronger woods to take the tension of the strings, which would in turn raise costs significantly. The use of a truss rod allows manufacturers to make guitar necks out of much softer woods or composite materials. It is also a means to stabilize and adjust the relief of the guitar neck (forward curve).

How many kind of truss rod?

There is no real answer, as anyone could make a new kind of truss rod, for example a licorice truss rod. Perhaps you mean that a truss rod could be under stress or under compression, or be designed for both.

It depends on the problem with your truss rod. I answered a question already on how to adjust the truss rod on a bass guitar. Search for "How do i adjust a truss rod on a bass guitar?" If your truss rod is broken or the threads are stripped search for "truss rod rescue kit". Before you buy it, read the details and watch the video so you know what you're getting into.

Which way do you turn the truss rod in a guitar to lower the strings?

NEVER adjust the truss rod in order to lower the strings. The majority of string height adjustment is done at the bridge on either the bridge posts or individual saddles depending on your guitar. The truss rod is only there to correct any humping or bowing in the neck, if you tighten it then the strings will appear to lower but that's only because you're bending your guitars neck back! This will render your guitar pretty much unplayable until it's sorted so if you're not completely confident you know what you're doing then it's best to just leave any truss rod adjustment well alone. If you value your guitar then seek the advice of a qualified or experienced luthier or repair guy.
