The Problem with a Low E String

If you find that your low E string tends to go out of tune quickly, you are not alone. This issue can be frustrating and often points to a specific area of your guitar that needs evaluation and possibly adjustment. There are several common causes for this problem, including issues with the string anchoring at either end of the guitar. Whether you own an acoustic or electric guitar, or even one with a tremolo system, this guide will help you troubleshoot and resolve the issue.

Why Does the Low E String Go Flat?

The low E string tends to become flat after a while, and this often points to problems at the ends of the string. For an acoustic guitar, the low E can be pulling past the securing peg. At the headstock end, you may have too many winds around the machine head post, which is a major cause of slipping. In guitars with a tremolo system, the string’s ball end could be a tight fit in the trem block and not fully seated. The nut and saddles on both acoustic and electric guitars are a problem with tuning stability if the string is binding in the slot. The correct size nut file can widen the slot, although care should be taken not to increase the depth unless necessary. Lubricating the nut slots with graphite can be done easily using a pencil lead.

Why Does the E String Sound Sharp When Fretted?

Another common issue is that the low E string tends to sound sharp when fretted, even after you tune it open. A new string may need to settle in or be stretched. The low E is the farthest reach and has a tendency to pull sharp if not fretted properly. This string might need more time to settle and stabilize its tuning.

Common Causes and Solutions

The low E string should not be any more problematic than other strings. However, several factors can contribute to this issue:

Tuning Machine Smoothness: Check the smoothness of the tuning machines. Loose Parts: Ensure that no parts are loose. Nut Slot Width and Height: Verify the width and height of the nut slots. Bridge Saddle Burrs: Check for any burrs on the saddle. String Age and Quality: Ensure your strings are of good quality and not old. Intonation Correctness: Check the intonation at the 12th fret and the first five frets. Proper Stretching: Ensure you properly stretch out the strings when installing them.

If no single factor is causing the problem, you might need to simply change the string. However, more serious issues related to the tuning peg, nut, or bridge saddle/anchor should be addressed. These are bigger deals than simply having 'crappy' strings, which can sometimes occur out of the package.

Conclusion

Whether your low E string is going flat or is sharp when fretted, it is important to address these issues promptly. By carefully checking the components of your guitar and making necessary adjustments, you can ensure that your instrument stays in tune and performs optimally. Remember, a well-maintained guitar is key to achieving the best sound and playing experience possible.
