Why does your guitar amp cut out?

Answer 1

Have you plugged it in properly?

Are you sure your power supply is not faulty?

Is the cable connecting guitar to amp faulty?

Is the volume (guitar or amp) at zero?

Is the amp very old?

Has the tube (if any) blown?

Damaged speaker?

You'll probably need to check the electrics then. Something may of come loose or worn out etc.

Answer 2

What kind of amp? A guitar amplifier (tube? solid state?) sound amplifier? a TV signal booster?

What is it doing that is not right?

With the question as it is, the only viable answer is "it might be broken."

Answer 3

for your sake i hope its the first and not the second possibility:

1) your cord running from ur jack on ur amp going to ur instrument is shot u need to buy a new one (this is often what the problem is)

2) ur amp is shot :( send it in to get fixed and hope to hell its not expensive

Answer 4

It could be many of problems it could be that there is a break in the alpha loom, the jack socket could have broken, switch could have gone, if you have active pick ups the battery could need changing.

if the alpha loom breaks its an easy fix but requires a little amount of skill with soldering and knowing what goes were with a diagram.

when something goes wrong with one of my guitar wiring loom i usual just buy a new one off various guitar shops and web-sights from 10 to 30 pounds.

If the jack socket has broken that also require soldering skills you can buy jack sockets for really cheep you can usually tell if the jack socket has broken because it makes a buzzing sound when plugged into an amplifier or it doesn't click in properly.

The switch is normally the first thing to break then the jack socket this again is a cheep and easy fix (soldering is needed) you can tell if the switch is broken by plugging the guitar into a amplifier strum the guitar and play around with the switch and keep strumming and if you get some sound on one channel and not on the other then you know. another way of knowing is the switch will not click into place.

Answer 5

There are dozens of possible reasons, but 97% of the time, it will be one of these:

The amp is unplugged.

The amp has a blown line fuse.

The guitar cable has a bad connector(s).

There is a broken wire in the guitar's output jack.
