Inspecting the Neck Aid
Earlier than you begin making changes, it is essential to know the idea of neck aid. Neck aid 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 stop buzzing whereas nonetheless retaining the strings near the fretboard for comfy enjoying. The quantity of aid is a matter of private desire and enjoying type, however typically, a neck aid of round 0.010 to 0.015 inches (0.25 to 0.38 mm) on the seventh fret is an efficient place to begin.
To examine the neck aid, observe 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 inform you how a lot aid your guitar’s neck has. If the aid is just too nice, you will must tighten the truss rod, and if it is too little, you will must loosen the truss rod. The next desk offers a common information for neck aid based mostly on enjoying type.

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 lengthen in the direction of the cranium.
4. Observe 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 Massive Greater than 3 inches It is essential to notice that the neck bow measurement can differ 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 test neck bow includes putting the capo on the first fret and fretting the string on the final fret, guaranteeing that the string is pressed towards the fretboard at each ends. The string must be away from the fretboard between the capo and the fretted observe. 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 aid.” The perfect neck aid 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 aid 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 way of 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 | Ideally suited | String is barely away from the fretboard between the capo and the fretted observe |
| Lower than 0.006 inches | Ahead bow | String touches the fretboard between the capo and the fretted observe |
| Greater than 0.012 inches | Again bow | String has a noticeable hole from the fretboard between the capo and the fretted observe |Inspecting the Fingerboard
After you have cleaned the fingerboard, you may 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 isn’t a bowing. Nevertheless, if the straight edge shouldn’t be flush with the fingerboard, then there may be bowing.
The quantity of bowing may be measured utilizing a feeler gauge. A feeler gauge is a skinny, metallic strip that’s accessible 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 suits 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 aid. The truss rod is a metallic rod that runs by way of the neck of the guitar. Tightening the truss rod will lower the neck aid, whereas loosening the truss rod will improve the neck aid.
You will need to alter the truss rod fastidiously. For those who overtighten the truss rod, you may harm the neck of the guitar. For those who undertighten the truss rod, the neck is not going to be steady and will probably be extra prone to bow.
Utilizing a Radius Gauge
A radius gauge is a specialised software 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. It is essential to make use of the gauge in a number of positions alongside the neck to make sure an correct measurement.
Suggestions for Utilizing a Radius Gauge:
- Place the gauge perpendicular to the fingerboard at completely different factors alongside the neck.
- Search for the semi-circle that almost all intently matches the curvature of the neck.
- Report the radius indicated by the matching semi-circle.
- Take a number of measurements to make sure accuracy.
- If the gauge doesn’t have a semi-circle that completely matches the neck, estimate the radius based mostly on the closest matching semi-circle.
- Contemplate the string gauge and enjoying type when deciding on a radius. Greater string gauges and extra aggressive enjoying kinds could require a bigger radius for optimum consolation and efficiency.
Radius Vary and Frequent Neck Bows:
Radius Vary (in inches) Typical Neck Bows 7.25 – 9.5 Classic and traditional guitars 10 – 12 Trendy electrical guitars 13 – 16 Acoustic guitars and a few trendy electrical guitars 17+ Compound radius necks, offering a flatter enjoying floor close to the nut and a extra curved floor in the direction of the physique It is essential to notice that the optimum neck radius can differ relying on private preferences and enjoying type. Finally, the very best radius for a selected instrument is one that gives a cushty and playable expertise for the musician.
Assessing the Truss Rod Adjustment

- Place the capo on the primary fret.
- 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 perfect 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 numerous neck bow situations:
Neck Bow Situation
Hole at seventh Fret (in inches)
Backbow
Larger 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 harm the neck.
Contemplating the String Top
The string peak, often known as the motion, considerably impacts the playability and tone of the guitar. A better string peak makes it simpler to play with out fret buzz however could make bending strings troublesome. Conversely, a decrease string peak permits for simpler string bending however could improve the danger of fret buzz. The perfect string peak is a steadiness between these components, and it might differ relying in your enjoying type and the precise guitar you’re utilizing.
Measuring the String Top
To measure the string peak, you should use a feeler gauge or a capo and ruler. With a feeler gauge, merely insert the gauge between the string and the twelfth fret. The thickness of the gauge that simply suits underneath the string is the string peak. For those who’re utilizing a capo and ruler, place the capo on the primary fret and measure the space between the underside of the string and the highest of the twelfth fret.
Adjusting the String Top
The string peak may be adjusted by elevating or decreasing the bridge. Most guitars have adjustable bridge saddles or truss rods that help you make these changes. If you’re not comfy performing this adjustment your self, it is strongly recommended to take your guitar to a professional technician.
