What is dual action truss rod?

What is dual action truss rod?

A double action or double action truss rod is a device inserted inside the neck, capable of recreating a concave or convex curvature on the fingerboard, independent of string pull. The operation is identical to that of a single action truss rod: turning the nut clockwise bends the fretboard in a convex way.

Is truss rod cover necessary?

It doesn’t need it every time, but sometimes the truss rod needs to be tightened, sometimes it needs to be backed off.

How do you use a double action truss rod?

To access and make adjustments to the truss rod, keep the capo on the first fret and remove the truss rod cover located behind the string nut at the headstock. A simple turn in one direction or the other using the appropriately sized wrench will dramatically change the tonality and overall playability of your guitar.

Which way do you turn truss rod to lower action?

To add relief to the neck, you’ll want to loosen the truss rod or turn the truss rod nut counter-clockwise. To reduce the amount of relief and make your guitar a little easier to play, you’ll want to tighten the truss rod or turn the truss rod nut clockwise.

Can you over tighten a truss rod?

Loosening a truss rod nut can’t harm anything, but over-tightening can. Loosening the truss rod adjusting nut simply allows the neck to relax and be pulled by the strings. No problem. If you over-tighten the nut, however, you can cause damage.

What is the purpose of a truss rod cover?

A truss rod keeps the neck straight by countering the pull of the strings and natural tendencies in the wood. When the truss rod is loosened, the neck bends slightly in response to the tension of the strings. Similarly, when tightened, the truss rod straightens the neck by resisting string tension.

How do I know if my truss rod needs adjusting?

Two primary signs tell you that your truss rod needs adjusting:

1. There’s a noticeable change in the action; the height of the strings over the frets has become either too high or too low.
2. Some strings buzz on the frets between the nut and the fifth fret.

Does the truss rod affect intonation?

Intonation is mainly controlled from your bridge, but adjustments you make to your truss rod can affect intonation. To prevent intonation issues, we try to aim for a slight relief. A slight relief in the neck creates low action in the higher frets while preventing fret buzz in the lower frets.
