Because Of The Type Of Pickups

Even though it is the buzz or hum from the amp, the most popular cause is because of your guitar. And the first one is the pickups that you are using.

The Reason

The single-coil of the pickups usually makes more hum and buzz. And if you think that it comes from the amp and you just adjust the amp, everything will be worse. Even when you turn the gain knob or turn the distortion on, nothing is improved.

In the case, you don’t see any different things of the shielding, your cable may have any things that need to be fixed.

The Solution

Because Of The Guitars’ Pedal

In this case, you don’t find out any troubles like the 2 situations above and your guitar has the pedal, now, you need to check it. You can know when it has this problem easily by rolling the volume to 0. If you still hear some buzz from the guitar. There are 2 things for you to check. They are the pedal and the amp. We will talk about the pedal first.

The Reason

First, it can be due to your pedal has high distortion. Besides, the volume knobs are also higher than their limit. From that, you can hear some terrible sounds like hissing or buzz. You can check by seeing the status of the pedals. If all pedals are similar to each other, the cause may come from the power. If it just has 1 or a few pedals are different, they may have malfunctioned.

The Solution

And here, we have a total of 3 ways to improve this issue. You can choose to try all or just one that you think will be effective.

The first thing that everyone can come up with it replace a new pedal. Because your pedal has a problem or the type of pedal is not good like what you want.

The Reason

This is not an uncommon issue for electric guitar players. If your guitar is in this situation, you will not hear the buzz when you touch the metal parts and strings like the 3 causes above. It may be because it is lacks grounding or its connection/soldering is not good. And it usually occurs with the old guitar more than a new one. In addition, another thing that can create that buzz is from the lights of the venue’s part.

The Reason

In the case your amp and the light use the same source of power, it will have noise both when you adjust the light and the amp. Besides, if it is connected to the fan, it will have noise too.

Secondly, the volume and the power of the amplifier are also important parts. Because an amp with lower wattage will cause less noise and buzz than another want with a higher wattage. It is the self-noise that you can see in every electronic device.

Thirdly, the tube amp is too old. Do you remember that how long you use it? An old tube amp will not only create the buzz but also the hissing. Although it is quite small and has less influence on the performance, it may still make you feel uncomfortable.
