Guitar amp buzzing no sound

Bad input jacks are one of the most common problems with electric guitars. The jack is held in place with a single nut at the base of the guitar.

Once this nut starts to come loose, the input will start to jiggle. This jiggling can break the two solder connections on the interior of the guitar and prevent transmission of sound from the pickups to the amplifier. If, when you insert your cable lead into the input, there is a deep humming tone or loud buzzing sound, it may be an indication that the input ground wire may have come loose.

The buzzing or humming is similar to when you touch the end of the lead to a metal object.

There is no completed circuit so a feedback loop is created which is the cause of the sound. Resoldering the connection should fix the problem.

If you are not getting a humming or buzzing sound but instead are suffering from a crackle while playing, it is a sign that the positive connection has come loose. If you are still able to generate sounds from the strings, the connection is not completely broken. The crackling comes from a lack of signal, or dead point, in the electrical cord. This dead point causes a crossover from the negative to positive soldered connections and delivers a surge to the amplifier creating the crackle.

A quick solder will fix this problem. A no sound problem indicates a full break in the positive connection on the interior of the guitar. The negative connection is still secure or there would be a humming or buzzing sound. The lack of positive input will prevent any transmission from running through the wire because there is no complete circuit.

Soldering may fix this problem but the jack may have burnt out and may need to be replaced. Before running out and getting a replacement jack, first check that the jack is the problem.

All of the symptoms that can be attributed to a faulty jack can also be indications of a bad cord.

Connect a different cord to the guitar and see if the problems persist. If oem vs cherry profile don't, then the problem is with the cord, not the jack.

Guitars Bass Amps Pedals Players. It has recently developed a popping, crackling sound when warmed up—even when there are no guitars or cables plugged in.

What is wrong? Could the valves be on the way out? Is it something more serious? Please help! Ken Morton Hi Ken, Thanks for your question. The Fender Hot Rod series of amps is a very popular one, possibly their most popular. There are many types of failures that cause this symptom. Input, footswitch and effects loop jack connections. Jacks are probably the most physically used and abused parts in the amp. They are soldered directly to the circuit board, but are also attached to the front panel via the jack nut.

This is usually not an issue unless the jack nut loosens due to vibration. Once the nut loosens slightly, the weight and motion of the guitar cable is supported solely by the circuit board solder connections. Over time, these connections can be compromised and cause crackling and an intermittent signal.

Broken solder joints on large components. Another vibration-caused failure, the solder connections of larger-sized components, such as large 5-watt resistors, can eventually be compromised from the constant vibration of playing, or simply a rough ride in your trunk or the band truck.

Simple tube failure. Tubes can fail in many different ways. Preamp tubes, on the other hand, will generally either become microphonic and make high pitched ringing or squealing noises, or will emit noises such as crackling and popping during idling. Stressed component failure. Some components become stressed over time when the typical operating parameters of the circuit are exceeded. This can easily happen with the failure of an associated component.

Take for example an output tube. While a typical 2-watt resistor used by many companies as an output tube screen grid resistor will function fine under most normal operating conditions, that resistor may be pushed past its capabilities by constantly playing the amp at very high volumes or by an output tube shorting.

This may cause excessive screen grid current to flow through the resistor, stressing it or causing complete failure. A stressed screen grid resistor can definitely cause crackling noises to occur.

As a side note, this is one reason to overbuild amps: to ensure the least possible chance of failures—using a 1-watt resistor instead of a half-watt resistor throughout the amp, for example, or a 5-watt in place of a 2-watt, etc. General component failure. Any electrical component can fail at any time, causing anything from compromised operation to a complete shut down. I did a bit of research on this question to see if there are any known failures of this particular amp that I had not personally encountered, and it turns out that there may well be.

According to the research, there may have been a bad batch of resistors used as plate resistors in the phase inverter circuit of the amplifier that were responsible for crackling noises in some amplifiers— a very strong possibility for the cause of your symptoms.

Having described the most likely candidates for the cause of your amp problem, I would say that based on your description of the amp needing to warm up first, and no guitar needing be connected, the most probable in your case is either 3 or 5.

The easiest way for you to do some basic troubleshooting would be to first purchase one replacement 12AX7 tube.Guitar hum can ruin recordings and be a real pain when performing live.

Read through the different questions to figure out which one applies to you, then read through the suggested solutions to help get rid of that annoying hum or buzz. If you want to change your pickups to improve your tone, check out this guide for a step-by-step tutorial on how to upgrade your pickups.

This is the most common type of hum you hear in electric guitars. As mentioned earlier, mains hum is the result of all the wiring in your home creating an electromagnetic field.

Dealing with this hum means figuring out what devices or wiring is causing the issue. For example fluorescent lights can cause a lot of hum. If you have fluorescent lighting in your room, try turning the lights off and listen if it changes the amount of hum you hear.

Another way you can figure out what is causing hum is to pick your guitar up and move it around your room. Use the guitar as a hum-homing device. Move it towards any electrical devices that are turned on and listen to the level of hum. Do you hear the hum increase when you move your guitar closer to the device? Sometimes turning a device like a desk lamp is all it takes to reduce the hum. You know the buzzing sound you hear when a lead is plugged into a guitar amp, but not plugged into the guitar?

Then if you touch the end of the lead the buzz disappears? That buzz is due to to a lack of grounding. Turns out the guitar was wired up poorly and rewiring the guitar completely removed the buzz. Different types of pickups will result in different levels of hum or noise. As you can guess from the name, a humbucker eliminates a lot of noise compared to a single coil pickup. A guitar with single coil pickups will definitely produce more hum or noise than a guitar with humbuckers.

If you have a guitar with a mix of single coil pickups and a humbucker, you should notice a big different in noise level when switch back and forth between the pickups. How you deal with this type of noise depends on what tone you want to have. You could change the pickups to something that produces less hum, but that also changes your tone. For example if you have a Telecaster which are typically noisychanging the pickups can make it sound less like a Telecaster.

If you use single-coil pickups and want to keep that sound, there are a couple of options. Alternatively, you can try shielding the pickups and components as much as possible.

If you have a budget guitar, a lot of the noise is probably due to the cheap pickups. Upgrading your pickups can have a significant impact on your tone and noise level. If so, that means you should turn your attention to your pedals or amp. Hearing hissing, hum or any low level noise is common when the gain is turned up on a pedal or the amp.

One of the downsides of playing with a high gain tone is the high gain can create and amplify noise. Electric guitars were designed this way because it was discovered early that touching a grounded part of a guitar cuts noise.

Here are five reasons why your strings are buzzing:.

This applies especially to barre chords, as you might not have worked up enough stamina and finger strength to make sure all the strings are making good contact. If you hit the strings too hard when strummingit can cause the strings to vibrate up and down too much as opposed to side to sideincreasing the chance of buzzing. If the new strings are thinner than before, the guitar will have a lower tension and is more likely to buzz and need some adjusting.

Make sure your guitar is set up properly. Taking it to a guitar shop can save a lot of time and head-scratching, because a technician can see if the buzzing is caused by low action, uneven frets, a bent neck or some other issue. Reducing buzzing is easy, you just have to pay attention to your technique and make sure your guitar is set up properly. Keep these tips in mind to enjoy a clean and buzz-free sound.

If your amp uses tubes, you must periodically check and replace the tubes, similar to replacing light bulbs in your house. If you hear a strange buzz coming from your guitar amp, it could be for a number of reasons.

Turn your amp off, then check each cable connection and wall power connection. If anything is not fully plugged in, that is the likely source of the buzz. Ensure all connections are secure and tight, then power the amp back on. If the buzz is still there, exclude any floor pedals or effects from the chain and plug your guitar directly into your amp. If the buzz is gone, then you have a bad cable somewhere in your chain that needs to be replaced, or your electronics need new batteries or have another issue.

Slowly add each electronic effect back into the chain, one at a time, until the buzz returns. The last effect you added before the buzz returns is the culprit; you can try different cables or remove that effect altogether until you have a chance to have it looked at.

Remember: the more effects and connections you have in your guitar rig setup, the more chances you have for problems. It only takes one bad connection to make the whole rig buzz. Troubleshoot the setup to see if you can pinpoint the source of the buzz. Move your rig to a different room and turn it back on. If the buzz is gone, then the source of the buzz was likely the electrical circuit you were connected to originally.

If the buzz is still there, try a different guitar if possible. If the buzz is gone, then the issue is with your guitar. If the buzz remains, try a new amp if possible to see if the issue is with your amp. If the buzz is still there with a new guitar and a new amp, try different cables. Cables deteriorate in performance over time and need to be replaced every year or so depending on how often you use them. If your guitar amp uses tubes, replace the tubes and try again.

Continue troubleshooting the issue by adding and removing different variables until you narrow down the source of the buzz. Check to see that the levels on your amp are set normally. If your gain, distortion or volume is turned up more than normal, it might be causing the buzz.

Turn the levels down and see if the buzz subsides. If it does not, the the levels are not causing the issue. Also check to make sure your distortion effects are not enabled. Distortion effects have a naturally buzz that you cannot hear when you are playing, but when the guitar is quiet and the distortion is on, you will hear a buzz from your amp.

A power conditioner helps regulate the electricity that your guitar rig uses. If you use a lot of electronics in your setup, a power conditioner will help you control all of the electricity and eliminate unwanted buzz that is a result of poorly distributed power. Without a power conditioner, you might be pulling too much power from the particular circuit you are plugged into, which can cause your amp to buzz or even short circuit if it is being pushed too hard without enough electricity.

Check the speaker cones on your amp. If one is torn, cracked, dented or out of place, it can cause a buzz. Take the amp to a musical equipment repair shop to assess the damage. If the damage is minimal, it can likely be fixed. However, if there is a large rip in the speaker, it may need to be replaced before it works properly again. To avoid ripping or damaging your speakers, purchase a hard shell amp case to keep your amp safely protected when you travel with it.

It can be buzz, hum, hiss, air-traffic control This Is Spinal Tapanyone? I'll start off by saying that guitar rigs are a noisy environment to begin with. Gain has a lot to do with noise, but if things are clean before it hits the gain stage, your rig can be quiet er.

There are so many ways noise can get into your rig. It can be a tangled web. Sometimes noise is just a side effect of what we are trying to achieve, but eliminating noise before it gets amplified will lead to better results in the end. Make sure your amp has a ground pin on the AC cable and your power source is properly wired and grounded. I carry one at all time. This will tell you if your power source is wired properly and that it is grounded.

You really want everything grounded; you don't want to become the ground; that would be bad. Most times when I'm on tour and having noise issues, it's because the house lighting rig is tied into the same power source as the back-line power. You can hear the lighting dimmers as noise in your amp.

When the lights are on percent, the noise goes away. This is poor planning on the venue's part. I can't tell you how many times I had to make the local crew fix the issue when I was on tour with Lou Reed. He didn't like any extra noise, and who can blame him? In a perfect world, you would have a power source dedicated to back-line with no lighting dimmers plugged in anywhere on the power circuit.

Some motorized devices like fans also can add noise. I also find that there can be a grounding issue between the back-line power and audio power. A perfect example is when an acoustic guitar is plugged into a multi-FX box that is plugged into an amp on stage, as well as a D.

When the D.
