How to Best Reduce Guitar Feedback
By Tony Olegro
Intentional feedback is an effect that's a very expressive and musical part of an electric guitar
, something that can't be recreated in a plugin. However, uncontrollable feedback is bothersome and is undesirable in recordings. Feedback is the high-pitched sound that comes from your speakers, usually when your guitar is right in front of the amp or a microphone is too close to the speakers; it can also be a consistent hum. It severely reduces the quality and professionalism of your recordings, and not many people would want to listen to a song with annoying sounds in it.
Knowing how to best reduce guitar feedback will make your recordings more professional and listenable, not to mention protect your ears during guitar recording if the feedback gets too loud. So, if you are having trouble with this nuisance called feedback and want to know how to effectively minimize it, our guide on how to best reduce guitar feedback will show you how...
What Causes Guitar Feedback
Before knowing how to best reduce guitar feedback, it's a good idea to know what causes feedback; that way, you'll better understand how to prevent it.
Feedback typically occurs when the guitar is right in front of the amp or a microphone is too close to the speakers. What happens is that a loop between an input and output becomes closed, and in this case the microphone or vibrating guitar strings are the input and the speakers are the output (the string vibrations are happening at particular frequencies, usually in the low end around 100-200 Hz or lower). Basically, the sound from the speakers reaches the input and is amplified again, hence causing an endless loop. This results in uncontrollable feedback.
Also, on an electric guitar, coils of the pickup degrade with time, eventually becoming microphonic. One of the reasons that coils degrade is that adjacent turns of the coil are insulated by lacquer, and even without external damage or poor treatment, it wears down over time, cracking and causing very tiny short circuits, thus creating feedback. Also, if the winding isn't uniformly tight, it loosens some turns of the coil that then vibrate and cause a lot of uncontrollable feedback.
