Buzzing and rattling and zings Oh My!
The sound of a guitar is something I think everyone knows but players in particular will have at some point been fixated on something that doesn't sound right. Often the player can spend days or weeks trying to find where the buzz/ rattle is coming from. In this exploration, we will delve into the myriad of reasons why a guitar may buzz and discover potential solutions. This is by all means not an exhaustive list.
The Bad String:
The most common culprit behind guitar buzz is often related to the strings. Factors such as old or worn-out strings, incorrect string gauge, or improper string installation can lead to buzzing. As strings age, they tarnish, change in the way they move and intonate. This ageing can cause vibrating against the frets or just not alow it to oscillate properly, resulting in an unwanted buzz. Ensuring regular string changes and proper installation is essential to minimise this issue. Even then, a brand new set of strings can have a bad string in the pack and that is really frustrating.
Action and Setup:
The action, or the distance between the strings and the fretboard, plays a crucial role in the playability of a guitar. If the action is too low, the strings may come into contact with the frets, causing a buzzing sound. Conversely, high action can also lead to buzzing, as pressing the strings down becomes more challenging. Achieving the optimal action requires meticulous adjustment of the guitar's setup, which includes the truss rod, bridge, saddle and more.
Fret Problems:
Fret Issues can be somewhat invisible but once checked over can provide an insight into why a guitar is buzzing. Fret wear, uneven frets, or poorly seated frets can cause strings to vibrate against them, producing an unwanted noise. Regular maintenance, such as fret levelling and dressing can address these issues and ensure a smooth playing experience.
Truss Rod :
The truss rod is a metal rod within the neck of the guitar that controls its curvature. If the truss rod is improperly adjusted, it can affect the neck's relief, causing buzzing issues. A neck with too little or too much relief can lead to string buzzes and rattles. Careful truss rod adjustments can help get the neck in the right shape (with all other factors combined) for a better feeling and playing experience. It also dictates the way a guitar feels to play quite significantly. Not only a poorly adjusted truss rod and cause unwanted sounds but a loose or ,at worst, a broken Truss rod will sympathetically vibrate inside the neck and make unwanted noises that can be tricky to track down
Nut Issues:
The nut, is another potential source of buzzing. If the nut slots are too low you will hear buzz on the open strings, a poor shape and size of nut slot can also cause the common “sitar” type sound. Upgrading to a properly fitted and well cut nut, or having the existing one properly filed and adjusted can help alleviate this problem.
Bridge and Saddle:
The bridge and saddle of an acoustic guitar play a crucial role in transmitting the strings' vibration to the top. For this to happen the saddle on an acoustic guitar needs to be at the correct height above the bridge for break angle, tension and with action taken into account. On occasion adjustments to the bridge may need to be made and if it's too far out a neck set may be the only option available. On electric guitars bridge and saddle arrangements vary widely and usually have many screws, springs, widgets and doodads. All of these on a moving plate directly affected by the strings themselves. That's a lot of bits to rattle and buzz
Environmental Factors:
Guitars are sensitive to changes in temperature and humidity. Wood expands and contracts with variations in environmental conditions. This can lead to changes in the guitar's setup and in some cases can lead to parts becoming unglued, This is more common in acoustic guitars where tops can split and braces can become loose, causing buzzing. Storing the instrument in a stable environment and using a humidifier or dehumidifier as needed can mitigate the impact of environmental factors.
Loose Hardware:
We touched upon this with the bridge and saddle but on so many guitars there are a bunch of screws, nuts, bolts, washers, electronics, knobs etc etc etc. all these need to be tight to avoid unwanted noises and buzzing so many times i have chased a buzz coming from what seemed to be the body of an acoustic guitar only to find out it was a loose tuner nut. Noises that appear from nowhere always start somewhere. Be methodical and tighten all that can be. Just be careful not to strip wood screws etc.
Playing Technique:
The elephant in the Studio. Sometimes, the issue might not lie with the guitar itself but with the player's technique. Heavy-handed playing, improper finger placement, or inadequate fretting technique can contribute to buzzing. Addressing these aspects through practice and possibly seeking guidance from a guitar Tutor can significantly improve your overall tone and most likely help prevent things like carpal tunnel and tendonitis. So get some tuition , Practice and play lighter. Loud is what Marshal Stacks were made for.
In Conclusion:
We have all faced poorly playing guitars, notes choking out, rattly open strings, etc etc. some simple things you can do when changing strings next time can be to get the screwdriver, some fretboard cleaner and a little polish, then go to town for a good old clean, start top to bottom and nip up what can be nipped, clean the tarnished rusty frets (Yep, I have seen fully rusty frets) and get the finger cheese of that fretboard. Clean the bridge and saddles, tighten up loose pots and string it up with a good set of strings, my favourites are D’addario XS Coated strings. They are pricey but sound great and last longer.
If you are still getting buzz, think about how you are playing your guitar. Then if you can't think of how to fix it or just want someone else to do it ( hell you want to play, not fix right?) then book it into a guitar tech to take a look.
Hoping this might explain a few things
