If your amp is humming but no sound is coming out, it can be a frustrating problem. There are a few possible reasons why this might be happening, and there are also a few things you can do to try to fix it.
Here are some of the most common reasons why your amp might be humming but no sound is coming out:
- Dirty power: If you are using a power strip or extension cord, it is possible that the power is dirty. This can cause a humming sound and can also prevent the amp from working properly.
- Ground loop: A ground loop is a common problem that can cause humming in amps. It occurs when there are multiple devices connected to the same power circuit, and each device has a different ground. This can create a loop of electricity that causes the humming sound.
- Faulty cable: If the cable connecting your guitar to the amp is faulty, it can cause humming and can also prevent the sound from coming out.
- Damaged amp: If the amp is damaged, it can cause humming and can also prevent the sound from coming out.
