Inspecting the Neck Aid
Earlier than you begin making changes, it is essential to know the idea of neck reduction. Neck reduction refers back to the curvature of the guitar’s neck from the nut to the physique. The curvature must be slight, permitting sufficient area between the strings and the frets to forestall buzzing whereas nonetheless protecting the strings near the fretboard for snug enjoying. The quantity of reduction is a matter of non-public desire and enjoying fashion, however usually, a neck reduction of round 0.010 to 0.015 inches (0.25 to 0.38 mm) on the seventh fret is an efficient start line.
To examine the neck reduction, comply with these steps:
- With a set of feeler gauges or a straight ruler, measure the space between the highest of the seventh fret and the underside of the string.
- Gently press down on the string on the 1st and 14th frets, utilizing a capo to carry the string down on the 14th fret.
- Measure the space between the highest of the seventh fret and the underside of the string once more, whereas the string is held down on the frets.
The distinction between the 2 measurements will let you know how a lot reduction your guitar’s neck has. If the reduction is just too nice, you may must tighten the truss rod, and if it is too little, you may must loosen the truss rod. The next desk offers a common information for neck reduction based mostly on enjoying fashion.

- Measure the hole between the underside of the string and the seventh fret.
The best hole for many acoustic and electrical guitars is round 0.010-0.015 inches (0.25-0.38 mm). If the hole is bigger or smaller, the truss rod must be adjusted accordingly.
This is a desk summarizing the standard measurements for varied neck bow situations:
Neck Bow Situation
Hole at seventh Fret (in inches)
Backbow
Better than 0.015
Straight
0.010-0.015
Ahead Bow
Lower than 0.010
At all times make small, incremental changes to the truss rod and permit the neck to settle earlier than re-measuring. Over-tightening the truss rod can injury the neck.
Contemplating the String Top
