Why B Strings Often Go Out of Tune on a 12-String Guitar: Troubleshooting Tips

Two B strings on a 12-string guitar are a common point of trouble, but the issue is not exclusive to these strings. Like all guitar strings, they may go out of tune due to various factors. In this article, we will explore the reasons behind this fact and provide solutions to keep your B strings in tune.

Understanding the Problem

Just like any other strings, the B strings on a 12-string guitar are prone to going out of tune. This happens for several reasons, primarily related to the setup and usage of the guitar. Here are some key factors to consider:

String Quality and Proper Installation

The quality of the B strings is crucial. If they are low quality, they are more likely to break or go out of tune. When installing the strings, make sure they are wound correctly on the tuning pegs. Incorrect winding can lead to issues with tuning. Many online tutorials can help you with this procedure, and if you encounter difficulties, the retailer from whom you purchased the strings can provide assistance.

Tuning Peg Inspection

The tuning pegs themselves can become worn or lose their proper fit, leading to out-of-tune B strings. Inspect these pegs for any signs of wear or looseness. If you notice any issues, tighten the pegs or have them adjusted by a professional.

Intonation and Bridge Issues

In some cases, the issue might not be with the B strings themselves, but with the guitar’s intonation or the bridge. If one of the B strings is going sharp, it could indicate an intonation problem. With fixed bridges, professional work may be required to correct this issue.

Additional Challenges with 12-String B Strings

For 12-string guitars, the B string is often the most troublesome to keep in tune. Here are some specific reasons why:

High Tension and Enhanced Sensitivity

In a 12-string guitar, the B strings have a higher tension than the other strings. This higher tension, combined with the additional strings, makes the B strings more sensitive to changes in tuning. The high tension can cause the strings to go out of tune more frequently and require more frequent tuning.

Major Third in Equal Temperament

The major third in equal temperament, which is the tuning system used in western music, is slightly sharp. This sharpness is more noticeable with the B string, being a major third above G. In musical settings without a piano or similar instrument, choirs and vocal ensembles often tend to sing the major third flat, indicating that the B string can be harder to keep in tune.

Personal Experience

My own experiences with tuning a 12-string guitar have shown that the B strings are more prone to going out of tune. Unlike my nemesis, the high G string, which is the lightest and most tension-dependent, the B string struggles more. Over the years, I have faced numerous instances where I needed to adjust the B string, highlighting its sensitivity.

Conclusion

While B strings on both 12-string and 6-string guitars can go out of tune, additional factors often make this issue more pronounced with 12-string guitars. Proper installation, regular inspection of tuning pegs, and addressing intonation and bridge issues can help keep your B strings in tune. Remember, consistent maintenance and attention to detail can significantly improve the overall tuning of your 12-string guitar.
