To gauge neck bow, you will want a straight edge, akin to a ruler or a spirit degree. Place the straight edge alongside the fingerboard, resting it on the nut on the high of the neck and lengthening it in the direction of the bridge. Observe the hole between the straight edge and the neck. If the hole is even on either side, the neck is taken into account straight. Nonetheless, if the hole is wider on one facet, the neck has a bow and requires adjustment.
Adjusting neck bow requires specialised instruments and abilities. In case you are not skilled in violin restore, it’s advisable to hunt help from a professional luthier. They’ve the required information and expertise to soundly and successfully appropriate the neck bow, making certain that your violin performs at its finest. Common neck bow gauging and adjustment are important elements of violin upkeep, extending the instrument’s lifespan and preserving its efficiency capabilities.
Inspecting the Neck Reduction
Earlier than you begin making changes, it is essential to grasp 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 retaining the strings near the fretboard for comfy enjoying. The quantity of reduction is a matter of non-public choice and enjoying model, however typically, 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 simply too nice, you may have to tighten the truss rod, and if it is too little, you may have to loosen the truss rod. The next desk supplies a basic information for neck reduction primarily based on enjoying model.

To measure neck bow with a ruler, comply with these steps:
1. Make sure the canine is standing nonetheless and in a pure place.
2. Find the seventh cervical vertebra (C7) on the base of the neck, which is the bony bump simply earlier than the shoulder blades.
3. Place the ruler horizontally throughout the again of the neck, parallel to the bottom and perpendicular to the canine’s physique. The ruler ought to relaxation on C7 and prolong in the direction of the cranium.
4. Notice the measurement on the level the place the ruler intersects the cranium. That is the neck bow.Canine Measurement Neck Bow Measurement Small Lower than 2 inches Medium 2-3 inches Giant Greater than 3 inches It is necessary to notice that the neck bow measurement can range barely relying on the canine’s breed and particular person conformation. Skilled groomers or veterinarians can present extra exact measurements and steering on neck bow evaluation.
Checking with a Capo
Utilizing a capo to verify neck bow includes inserting the capo on the first fret and fretting the string on the final fret, making certain that the string is pressed in opposition to the fretboard at each ends. The string must be away from the fretboard between the capo and the fretted be aware. If the string touches the fretboard, the neck has an excessive amount of ahead bow. Conversely, if there’s a noticeable hole between the string and the fretboard, the neck has an excessive amount of again bow.
Measuring Neck Bow
To precisely measure the neck bow, place a straightedge alongside the size of the fretboard from the nut to the bridge. Measure the space between the underside of the straightedge and the highest of the string on the seventh fret. This measurement is usually known as the “neck reduction.” The best neck reduction varies barely relying on the instrument and the string gauge, however typically falls throughout the vary of 0.006 to 0.012 inches (0.15 to 0.30 mm). A ruler or a devoted neck reduction gauge can be utilized for this measurement.
Adjusting Neck Bow
To regulate the neck bow, use the truss rod, which is a metallic rod that runs by the middle of the neck. Turning the truss rod clockwise tightens it, which reduces ahead bow. Turning it counterclockwise loosens it, which reduces again bow. The quantity of adjustment must be made progressively, and the guitar must be tuned and checked for intonation earlier than making additional changes.
| Measurement | Bow | Description |
|—|—|—|
| 0.006 – 0.012 inches | Very best | String is barely away from the fretboard between the capo and the fretted be aware |
| Lower than 0.006 inches | Ahead bow | String touches the fretboard between the capo and the fretted be aware |
| Greater than 0.012 inches | Again bow | String has a noticeable hole from the fretboard between the capo and the fretted be aware |Inspecting the Fingerboard
After getting cleaned the fingerboard, you’ll be able to examine it for any indicators of bowing. To do that, maintain the guitar in entrance of you and place a straight edge alongside the fingerboard, from the nut to the bridge.
If the straight edge is completely flush with the fingerboard, then there is no such thing as a bowing. Nonetheless, if the straight edge shouldn’t be flush with the fingerboard, then there may be bowing.
The quantity of bowing could be measured utilizing a feeler gauge. A feeler gauge is a skinny, metallic strip that’s obtainable in quite a lot of thicknesses. To measure the bowing, place the feeler gauge underneath the straight edge, on the level the place the straight edge shouldn’t be flush with the fingerboard.
The thickness of the feeler gauge that matches underneath the straight edge is the quantity of bowing. For instance, if a 0.010-inch feeler gauge matches underneath the straight edge, then the fingerboard is bowed by 0.010 inches.
If the neck is bowed, you should use a truss rod to regulate the neck reduction. The truss rod is a metallic rod that runs by the neck of the guitar. Tightening the truss rod will lower the neck reduction, whereas loosening the truss rod will enhance the neck reduction.
It is very important alter the truss rod rigorously. For those who overtighten the truss rod, you’ll be able to injury the neck of the guitar. For those who undertighten the truss rod, the neck is not going to be secure and might be extra prone to bow.
Utilizing a Radius Gauge
A radius gauge is a specialised instrument designed particularly for measuring the radius of curved surfaces, together with the neck bow of a stringed instrument. It consists of a sequence of concentric semi-circles, every representing a special radius.
To make use of a radius gauge, merely align the gauge’s semi-circles with the curved floor of the neck. The semi-circle that most closely fits the curve signifies the radius of the neck.

- Fret the string on the twelfth fret to create a straight line with the string.
- Slide a straightedge throughout the string, parallel to the frets.
- 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.
Here is a desk summarizing the standard measurements for varied neck bow circumstances:
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 Peak
The string peak, also referred to as the motion, considerably impacts the playability and tone of the guitar.
