Amp buzz is a common issue that plagues guitar players of all skill levels. It’s a high-pitched humming or buzzing noise that can be heard when playing an amplified guitar. This noise can be distracting and can take away from the overall quality of your sound. In this guide, we’ll explore the root causes of amp buzz and provide practical solutions for eliminating it.
##What Causes Amp Buzz?
There are several common causes of amp buzz, including:
Ground loops: Ground loops occur when there is more than one path to ground in your signal chain. This can happen when your guitar is connected to an amp via a cable that is not properly shielded.
Poorly maintained equipment: Over time, dust and grime can accumulate on the internal components of your amp and guitar, leading to poor electrical connections and increased amp buzz.
Electromagnetic interference: This can be caused by nearby electronic devices, such as computers or cell phones, that emit electromagnetic fields.
##Eliminating Ground Loops
One of the most common causes of amp buzz is ground loops. To eliminate this type of amp buzz, you’ll need to break the ground loop in your signal chain. This can be done by using a ground lift adapter, which separates the ground connection between your guitar and your amp.
Another way to eliminate ground loops is to use a balanced cable, which uses two conductors (positive and negative) to carry the audio signal, instead of the single conductor found in unbalanced cables. This reduces the potential for interference and can help to eliminate amp buzz.
##Properly Maintaining Your Equipment
Another important step in eliminating amp buzz is to properly maintain your equipment. This includes regular cleaning and upkeep of your amp and guitar. Make sure to dust and wipe down your equipment regularly to prevent dust and grime from building up on the internal components.
It’s also a good idea to have your amp serviced by a professional technician every couple of years to ensure that all the internal components are in good working condition and to help prevent amp buzz from occurring.
##Reducing Electromagnetic Interference
Electromagnetic interference (EMI) can also be a cause of amp buzz. To reduce EMI, try to keep your amp and guitar as far away as possible from electronic devices that emit electromagnetic fields, such as computers or cell phones.
It’s also a good idea to use high-quality cables that are designed to reduce electromagnetic interference. These cables use special shielding to block out interference and can help to eliminate amp buzz.
