Common Reasons for Guitar Amp Cutting Out

Guitar amps could be making cutting-out sounds for many reasons, but loose cables, joints, or soldering points could be the culprit. Poor quality amps with poor speakers are also more likely to cut out. Impedance issues may also cause cutting out. 

Your Cable Is Not Firmly Plugged In: Constant cutting out sounds could be as simple as you not plugging in properly. Start by checking and confirming that you connect your cables firmly and properly. Check for firm connection on both sides, the amp and the guitar itself. When the cable is securely plugged in, you should hear a solid clicking or “pop” sound. 

Your Cable Jack May Be Dirty: At times, your cables may develop rust or catch some oxidation if left in humid conditions for too long. As a result, when plugged in, these rusts and oxidation may interfere with the signals sent from your guitar to your amp, causing cutting-out sounds. 

Check both ends of the cable. Observe if there is the development of rust or oxidation on your cable jacks. If yes, consider scrubbing and lightly sanding your cable jack using Scotch Brite and high grit sandpaper. 

Your Cable May Be Faulty: If you have firmly plugged in the cable on both sides, but your amp still cuts out, you may have an issue with your cable. If you have a spare cable, consider swapping the cable and see if you hear any cutting-out sound again. If not, you can confirm the old cable has issues. 

To double confirm this, you may try to plug the old cable into another amp and see if the cutting-out sounds continue. If yes, you can toss away the cable because it is confirmed to be faulty.

Faulty Guitar or Amp Jack(Socket): If you have swapped a new cable, and yet the cutting-out sounds continue to show up, the next step is to think about your guitar or amp socket. To diagnose this better, it may help if you have a spare guitar and an amp

Start by swapping to another guitar. If the cutting-out sounds are gone, then chances are it’s your guitar jack that is faulty. If not, keep the same guitar, and swap into another amp. If the cutting-out sounds are gone, it may be your amp jack. 

As usual, double confirm this by plugging both guitars into the same amp and plugging both amps into the same guitar. You can now confirm very well which is faulty by this time – the guitar or the amp. 

Loose Soldering Joints: Suppose there is still no logical explanation as to which is faulty. In that case, then there is a likelihood you have a loose soldering joint on either the amp or the guitar. This may be rather technical, so you may need to take your amp and guitar to a technician to diagnose and see. 

As a start, you may think about if you recently dropped your guitar or amp, the impact may have loosened the soldering joint. Take that device and have it checked first. 

Faulty Grounding Wire: When having your amp checked by a technician, ask the person to give the grounding wire on your amp, as a faulty grounding wire may also cause the amp to cut out. 

If the ground wire is loose, electricity can not leave the amp after it has been used to power something. This could cause your amp’s failsafe to trip and turn off the amp because the voltage is too high.

Incompatible impedance: If you are using a separate amp and speakers, ensure that the impedance rating of both the amp and the speakers is the same. If you put a speaker with a low impedance on an amp with a high impedance, the sound will cut out (and vice versa). 

Low-Quality Amp And Speakers: Suppose you are the type that likes to shred your guitar at a high volume. In that case, you may consider to spend some money in a better amp. This is because cheap speakers may not be able to work well under high voltage. Consider investing in great amps from makers such as Vox, Laney, Mesa Boogie, or Marshall.

Diagnosing the Problem: State Guitar vs. Modelling Guitar Amps

Knowing how to diagnose the problem when your guitar amp keeps cutting out is essential. There are different types of amps to consider: solid state (state guitar) amps and modelling (digital) guitar amps. While both solid state and modelling guitar amps have their own unique features and sound, they also have different potential issues that can cause them to cut out. Let’s look at how to diagnose these issues for both types of amps.

Solid state guitar amps, such as the popular Fender Mustang series, are known for their simplicity and consistent sound quality. These amps use solid materials like silicon to amplify the audio signal, unlike their tube counterparts. Common reasons for a solid state amp to cut out include overheating, electrical issues, and faulty components. If your amp is overheating, ensure that it has adequate ventilation and isn’t positioned near heat sources. If you suspect an electrical issue, check the power supply and cables for damage. It’s also a good idea to check for any loose or worn parts, such as volume knobs or input jacks.

On the other hand, modelling guitar amps like the boutique variety, utilize digital technology to emulate the sounds and feel of traditional tube amps. These amps require more attention to details, as they rely on more complex circuitry and software to produce their sound. In the digital realm, amp cutting out can be caused by software glitches, firmware updates, and a variety of other technical issues. To resolve these problems, check the manufacturer’s website and forums for updates and known issues. Pay attention to essential maintenance tips and firmware update announcements to ensure your amp stays running smoothly. Also, confirm your amp is connected securely to your guitar and view the settings for possible issues.

Lastly, remember that both types of amps can experience issues with volume pedals and other external gear. Check all connections and cables to ensure proper function and reduce potential points of failure. By understanding the characteristics and potential issues of state guitar and modelling guitar amps, you can more effectively diagnose and address issues that may cause your amp to cut out. Keep these essential maintenance tips in mind and be ready to troubleshoot whenever your guitar amp starts giving you trouble.
