The most annoying thing in the bassist’s life is the unwanted noise that spoils the bass outcome. And today, I am going to tell you everything which gives you answer of why is my bass amp buzzing.
Here in this article, I mentioned almost all the reasons that cause a buzz in the bass amp and also all the methods which I personally used to fix the buzz of my amp.
So, why is my bass amp buzzing?
Defective capacitors or cables, poor quality sound sources, loose connections, improper amp settings can cause buzzing. And if signals are unparalleled, earth cables are disconnected, signals are unmatched then also the buzz is produced in the feedback of amp.
Buzz or hum created by the bass amp is something that no one wants. Before telling you the solution to this problem let me tell you first the reasons that cause a buzz in a bass amp.
The amount of buzz formed depends on the design and state of a bass amp. Buzz can be formed if you use poor Fx units and pedalboards, if the outlet of the bass amp is not perfectly earthed, and if the AC supply is not well. Your bass can also be the reason behind the buzz formation in your amp.
Nearby radio towers can also disturb your bass amp output due to radio frequency interference.
Along with this, bright EQ settings, high gain, and high volume settings can also cause hum. But hum formed due to such settings cannot be fixed. Either change the settings of your amp or tolerate the buzz.
Two Basic Types of Hum or Buzz
Almost every bass amp forms a little bit of buzz after a particular period of time. So to fix this issue we have to figure out exactly which type of buzz or hum we are dealing with.
Turn the volume of your bass amp up and down and check whether the buzz also varies according to it. If yes, then you are dealing with the main buzz ( 50-60 Hz buzz ). Such hiss is formed due to cable problems, poor protection shield, or vicinity of magnetic fields. The main buzz can also cause due to input sources (e.g turntable). By removing or replacing such input sources you can easily fix this issue.
2. Ground loop buzz (120 hz buzz)
On changing the volume of the amp if buzz does not vary then maybe you are facing 120 Hz buzz. To check this out remove all the inputs and cables connected to your bass amplifiers except speaker cables and AC plug. And now if hiss goes away then definitely it’s a ground loop buzz.
So now reconnect all the cables one by one and check when hiss or hum comes back. By doing this you can easily figure out the piece of equipment which is defective and needs to be replaced.
How to Fix My Buzzing Bass Amp?
It’s very irritating and bothering when an unwanted noise started forming from your bass amp. You cannot completely get rid of this buzz but you can minimize it. Here I will tell you some tricks and suggestions which you can try to solve your buzzing issue.
1)Limiting External Interferance
A) Change gain settings
The very common reason for hum formation can be the gain settings of your bass amp. Basically, gain settings make the audio louder by increasing the power of amp signals. Find the gain dial of your bass amp and turn it slowly anticlockwise till the hum goes away. If still not issue solved it means buzz is formed due to other reasons.
B) Turn offinterference sources
The frequency emitted by Bluetooth devices, fluorescent lights, dimmer switches, and computer monitors in your room may cause interference for bass amps. If they are forming a buzz then switch off such sources one by one and check which device is creating it.
C) Find the area of least interference
You have to find out the place in your room which is far away from the interference source. Connect your bass amp with all its equipment and then move it around the room. When you are close to a source of interference obviously bass amp is going to create louder hiss and hum. Like this, you can analyze the volume of buzz and find out the perfect place with the least interference.
D) Plug equipment in thesame outlet
Hum can be formed if you plug cables of amp and equipment into different outlets. Now unplug your bass amp and reconnect it at such a place where all cables and equipment fit on one outlet. Use a power strip for protection if you do not have sufficient sockets for all equipment. And never ever remove grounding prongs as it provides you protection from electrical shock.
E) If you can’t plug equipment into the same outlet then use buzz reducing adaptor
If you want to connect equipment to a different outlet then use an adaptor. Connect this adaptor to the socket of the outlet and then plug the amp cable on it. Basically, this adaptor balances out the frequency and reduces the buzz.
2) Adjusting Cable Connections
A) Use shortest Cables
Use cables that are short as much as possible for connection as it helps to reduce extra unwanted buzz. But make sure that these cables are not tightly dragged because it may harm the internal wiring of the amp. Avoid using long cables because they pick up frequencies more easily and form interference.
B)Clip a ferrite choke
Some cables already have a built-in ferrite choke while some do not. A ferrite choke is a small cylindrical clip that cuts off unwanted frequency. You can easily buy this choke at a market at an affordable price. Attach this choke by leaving a distance of 2-3 inches from both sides of the cable.
C) Wiggle the connector cables
To check whether buzz is forming due to loose connections wiggle the cables. Hold the end of cables attached to amps and shake it slightly here and there and listen does it cause any interference. If yes then all you need is a screwdriver to fix a loose jack. And if you are not able to tight it with a screwdriver then the only solution is a cable replacement. Because loose jacks mainly cause buzz as they are slightly parted from the circuit.
D) Use different cables
Replace the old connector cables with newer ones. Because old damaged cables may be the reason for buzz formation. I always keep a pair of extra connecting cables with me which helps me many times to get rid of unwanted noise.
E) Solder wire connections
While doing this always remember to unplug the amp so that there is no risk of any electrical shock. Wiggle the wires inside the bass amp and check which one is loose. If you find anyone then fix it using soldering iron. After sometime when the solder hardens check the difference in buzz.
F) Check loose connection on your Equipment
After using all the above methods still, buzz does not go away then maybe equipment you are using with your bass amp are the real culprit Firstly unplug the equipment and switch off them for safety purposes. Remove the cover and solder the wire if you found any loose wire inside it. If you do not know how to do this on your own then please take professional help.
If still issue is not solved then I will suggest you watch this below video once may it helps you.
