Why the Guitar Amp Cuts Out Randomly?


Every guitarist wants an amazing playing experience, but that’s impossible when the musical instrument’s amplifier cuts out randomly.

It explains why you are looking for a solution that will fix this problem once and for all.

Unfortunately, there is no direct answer to that since there are various reasons why your guitar amp cuts out randomly.

From tubes to audio sockets to the quality of the speaker to the cables, here is a detailed discussion on why the guitar amp cuts out randomly.

We will also discuss possible solutions, so keep reading.

Why Does My Guitar Amp Cut Out Randomly

If you notice that your guitar amp keeps cutting out randomly, the culprit could be one of the following incidences;

Faulty Electrical Outlet

Before assuming your guitar amp has an issue, confirm that the electrical outlet you plugged it into works excellently.

You can verify that by plugging it into another electric outlet, and if the problem goes away, it is the issue, and you have found the solution.

Cable Issues

Again, here’s a reason with nothing to do with your guitar amp.

Check whether its jack is good, and don’t overlook the cord’s cable.

If one or even the two are faulty, they need a replacement for the guitar amp to stop misbehaving.

If you aren’t sure, try another power cord and see if there are any changes.

Alternatively, try using the cable with another guitar amp.

If you will replace the power cord, buy a thicker one next time to withstand outside pressure, such as when you accidentally step on it.

Besides power cables, the guitar cable can also be a problem, thus compromising the signal and failing to block noise excellently.

Sometimes, the cable works well but is loosely connected to the audio socket.

If that’s the case, connecting it firmly will solve that issue.

The Room Effect

In other instances, it may be the room where the guitar amp is causing it to cut off randomly.

That’s why guitarists will notice that the guitar amp misbehaves while playing in a certain room.

In most cases, the rooms are usually small, and the sound has a substantial buzz.

The reason for that is the reflection of the sound from the room’s walls back to your guitar amp.

Changing its position or the room can make a huge difference.

Dysfunctional Tone Pots

Your guitar and amp pots can make sounds that keep cutting out if they are not working properly.

It could be a single-tone pot or more; you can identify that by turning the pots around and observing whether the sound will cut out.

Broken Solder Joints

The solder joint on the guitar amp’s circuit board can break for various reasons.

They include physical damage, extremely high or low humidity or rapid temperature change.

Under such circumstances, the amp starts cutting out randomly.

Bad Jacks

For instance, plug-in jacks often loosen, and wires can detach from them.

Amp jacks that allow you to plug in your phone or guitar cable and the amp sockets also get bad.

Damaged Guitar

The guitar amp cutting out could indicate that it is time to buy a new guitar.

The current one is old and damaged and thus needs repair or replacement.

Cheap Guitar Amps

If you drive a guitar amp at high volume, it may start cutting out if it can’t handle high voltage.

Unfortunately, that only occurs in poor-quality amplifiers.

Incompatible Impedance

The issue arises when dealing with independent speakers and amps.

Unless the impedance of the pair matches, expect cutting out.

For example, avoid a low-impedance amp, a high-impedance speaker, and vice versa.

Loose Grounding Wire

It prevents electricity from flowing from your guitar amp, leading to voltage overload.

Consequently, the amp’s failed sail trips cause cut out.
