| Adjustment | Results on Neck Aid |
|---|---|
| Over-tightening | Reduces neck reduction, probably inflicting back-bowing |
| Underneath-tightening | Will increase neck reduction, probably inflicting forward-bowing |
Checking the Neck for Stability
8. Checking for Aid
To test for neck reduction, maintain down the low E string on the first fret and concurrently press down on the excessive E string on the final fret. If the string is simply too tight (convex), the strings will not buzz in any respect. If the string is simply too free (concave), they’ll buzz in opposition to the frets. Ideally, there needs to be a slight quantity of reduction, permitting the strings to vibrate freely with out buzzing.
To measure the reduction, use a feeler gauge (a skinny, metallic strip) and insert it between the string and the seventh or ninth fret whereas urgent down the strings on the first and final frets. The feeler gauge ought to match snugly, however not too tightly. A measurement of 0.010-0.012 inches (0.25-0.30 mm) is mostly thought of optimum for many guitar necks.
| Neck Aid | Measurement | Strings |
|---|---|---|
| Slight Aid | 0.010-0.012 inches (0.25-0.30 mm) | Vibrates freely with out buzzing |
| Too Tight | No buzz | Strings is not going to press down correctly |
| Too Unfastened | Buzzing in opposition to frets | Strings vibrate too freely and produce undesirable sounds |
