Try moving the HD in relation with the amp with the volume down and see if there is. Two options are given later on in this guide. As explained earlier, electronic devices can interfere with your guitar’s signal and produce noise. If you have fluorescent lighting in your room, try turning the lights off and listen if it changes the amount of hum you hear. Why does my guitar hum when I turn the volume down? An effective way of preventing a lot of interference from ruining your tone is to shield your guitar’s electronics. My current 2 Lesters also have some hum when turning volumes down. Not disagreeing with previous explanations but I would look at the wiring in the guitar for sure. If you only have a bit of hum you want to filter out of your tone, the NS-2 will do the job. When you turn down the volume (even just a bit), the high end or treble loss isnot proportionate! Does this point more towards unmatched coils? This is the natural behavior of the potentiometer and it will happen with your Tone control as well. If I turned the pot up at all, the noise went away. I hope someone can answer this one. Use the guitar as a hum-homing device. The pickup is a bar magnet wrapped with thousands of turns of wire, forming a coil. This means it tries to remove the noise even while you’re playing – which is very different to a noise gate. I'm sure this has been answered before, but Ihaven't been on the thread or forum for years. I was able to isolate the device that injected the #1 hum, where the less loud/noisy hum still exists without any inputs. The room has a TV but I tried other rooms, and that guitar does that on my 3 different amps. When I turn my guitar volume knob down even just a little, the sound gets muddy. Definitely try another guitar if possible as suggested. If you’re hearing noise, buzz or hum that’s as loud or louder than your guitar, you may have a bad ground inside your guitar. So hum can get in best when it's in the middle. Only problems I can discern is a lot of (but not intolerable) hum - I think this is because the pickguard has bugger-all shielding - and the volume knob doesn't go all the way to zero. Changing the input does not stop the hum 3. Removing input does reduce the hum, but switching to the stable, low and not changing with volume hum. Of course it is annoying when you’re not touching the strings as you will hear the hum come back. It’s part of how electric guitars are designed and nothing to worry about. How to get rid of hum and eliminate other noises from your audio and video systems Don't let buzz, hum, or hiss ruin your AV experience. If the hum or noise increases when you touch your strings, that’s a sign something is wrong with the wiring of your guitar. Yes it is possible to play a guitar with the volume under ten (just some info for the metal shredders out there). There are a few different causes of hum or noise so your first step is to figure out what type of issue you’re dealing with. It doesnt matter if a guitar is plugged in. If you want to learn more about noise suppressors, noise gates and other useful tools you can add to your rig, check out the Guitar Effects Course here. not hum-cancelling. The hum is the same loudness regardless of the volume setting. If you have a budget guitar, a lot of the noise is probably due to the cheap pickups. but decided to leave my Zappa hallucinations for later). 1. Cranking the gain too high is a common rookie mistake so try to find the sweet spot that gives you a balance between definition and grit. Upgrading your pickups can have a significant impact on your tone and noise level. Where changing the volume also changes the level of the hum. If you’re a live performer, a noise gate like the Silencer is a nice tool to have available on your pedalboard. The downside is that the hum isn’t removed while you’re playing. Also check to make sure your distortion effects are not enabled. Pretty sure the wiring is … interference being picked up after the guitar. Thread starter SkidFx; Start date Aug 14, 2020; S. SkidFx ... particularly the volume controls - does the hum vanish when the master volume is turned down - if so does it vanish when either, or both, of the preamp volumes are turned down… Turns out the guitar was wired up poorly and rewiring the guitar completely removed the buzz. Note: if you don’t feel confident about electronics, give your guitar to somebody who does for them to shield it properly. The noise wants to complete it's circuit as "easily" as possible. It by no means eliminates them. Flip the polarity switch on the guitar amp to the lowest-hum position. My Epi Dot is fairly quiet but the wiring is not what you'd call high quality either. Hearing hissing, hum or any low level noise is common when the gain is turned up on a pedal or the amp. If you use single-coil pickups and want to keep that sound, there are a couple of options. If you know what you’re doing, check the wiring. One potential option for removing any noise is to use a pedal. Built into the guitar, under the strings, is a magnetic pickup: a transducer that converts the strings’ vibration into an electrical signal. Just to clarify, the hum should stop when I roll down the volume knob to 0, so it should be grounded. I never understood this myself. A well made and wired guitar shouldn’t really have a need for extra shielding. This means when you touch your strings, bridge, jack or metal volume/tone knobs, your hand and body also become connected to the ground loop. Check for poor ground's, loose nuts, even a broken center tap to the transformer. 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. My other guitars are normal, when the volume pot is on 0 they are muted. Simply buy a roll of copper foil tape and completely line the inside of the guitar’s cavity and back of your pickguard. A good way to divide and conquer is to turn the volume control(s). Yes it is possible to play a guitar with the volume under ten (just some info for the metal shredders out there). There’s nothing that ruins your guitar tone more than hum, buzz or noise. How to get rid of hum and eliminate other noises from your audio and video systems Don't let buzz, hum, or hiss ruin your AV experience. One guitar only lets me go to about 7.5 on the volumes, while the new one lets me go down to just below 9 on the volumes before I notice some hum. Use an EQ Pedal. So guitar makers simply soldered a wire on to the bridge so whenever the guitarist touched the strings, it would remove any noise. You could change the pickups to something that produces less hum, but that also changes your tone. A faulty, humming preamp tube can be isolated this way very quickly. While the ideal situation is to remove the noise at the source, adding one of these pedals can produce great results. Quote from: duck_arse on June 28, 2013, 12:14:56 PM, Quote from: R.G. I have a Tophat Supreme 16 that gets a really nasty hum the louder I turn it up. On the Hiwatt, if you've checked the obvious, tubes, caps, transformers, bias, there are a few places to look. Guitar Gear Finder is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, Amazon.ca, or Amazon.de. Now instead of all the components merely being soldered together like before, they’re all connected by the shield. One of the downsides of playing with a high gain tone is the high gain can create and amplify noise. If you notice a big drop in hum level when you touch your guitar’s strings, that’s normal. Second, when either volume pot is turned down the hum increases dramatically rather than disappearing as the pickup sound does. Dealing with this hum means figuring out what devices or wiring is causing the issue. The guitar end goes from nearly zero (when volume pot is at minimum) to 125K to 250K in the resistive middle, back down to a few k at the maximum of the pot rotation. 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. You might notice some blobs of solder on the back of the volume and tone pots. So instead of having to hit multiple pedals, you simply hit one and you can activate or deactivate the entire effects loop. Clasp your hand around the neck of the guitar. If you are trying to understand why the hum lessens when the tone control is rolled off, it is because the passive type electronics use the tone control to remove part of the frequency spectrum (the high end), to give you tonal changes. It’s normal for hum to decrease when you touch your strings. Guitar Tube Amplifier Volume Intermittent Volume drop. This is another situation where a buffer in the guitar helps. New and exciting innovations in current technology! In other words, a small cut in volume creates a far greater loss in your guitar’s treble response. Hearing hissing, hum or any low level noise is common when the gain is turned up on a pedal or the amp. A noise gate or suppressor is the next best thing and can make a big difference in your tone. If you find lowering your volume also darkens your overall tone when backed down, you can add a simple EQ pedal to your signal chain to compensate. If you’re in the US, listen to this clip of a 60Hz signal: If you’re outside of the US, listen to this clip for an example of a 50Hz signal: If the pitch of your hum sounds similar to one of the above clip, that’s a sign that it’s a mains hum issue. Turn the levels down and see if the buzz subsides. No sound means nothing coming out at all. Q: Why Does My Amp Hum When The Guitar’s Volume Knob Is At Zero? For the price of a cheap roll of foil it’s worth giving a go. This means when you stop playing, instead of hearing hum or buzz, you will hear silence. At a gig the other night I had a buzz coming from the amp only when the volume pot (on the guitar) was turned down. A wire connects all of them together to form a ground loop. If this stops the hum, it is a sign that the pickups are responding to radio-frequency interference. Check the course out if you’re serious about improving your tone. Use an EQ Pedal. But a far more effective way to deal with hum is to shield the components completely. It's hum free except for when I turn the volume down to 5-6 when some hum/buzz is heard. very noisy, whnever i stop strocking the strings, the hum comes back.. in both neck and bridge pickups.. Changing the input does not stop the hum 3. Page created in 0.141 seconds with 26 queries. Then if you touch the end of the lead the buzz disappears?

I got the amp off ebay and they said the hum is due to a blown tube. The pickup does have a cover. If the hum changes levels as you do this, then the source of the hum is something that affects the stages of the amp before the volume control. Turn up the guitar’s volume and treble controls so that the guitar signal overrides hum and noise picked up by the guitar cable and guitar amp. The homemade guitar I built had a massive reduction in noise when I shielded the electronics this way. No signal, but hum, means some of the circuit is working, and is something that can be tracked down. There are a few ways you can deal with this issue: Your guitar’s strings, bridge and jack are are all connected together in a ‘ground loop’. If you find lowering your volume also darkens your overall tone when backed down, you can add a simple EQ pedal to your signal chain to compensate. Assuming all is well with the cable, now turn up the guitar's volume to maximum, hold the strings in a normal playing fashion and listen again. Also, running your volume lower on single coil guitars cuts down on the 60-cycle hum in the signal. Then when you start playing again, the noise gate deactivates and you have your untouched tone. I did use a treble bleed cap on the volume pots to get the clean highs with the volume turned down. It does roll off quite a lot, but you can still hear the guitar at its minimal setting. When they begin to wear out, first they will hum. It’s not perfect, but it will cut the noise as soon as you stop playing. "Take these three items, some WD-40, a vise grip, and a roll of duct tape. I have read and would like confirmation on it; that volume controls act as a voltage divider which cause this hum situation. Use less gain. Noise suppressors work by filtering out noise in your tone. The potentiometer (or “pot”) leaks high end frequencies to ground relative to its value. You'd prefer that it find it easier to do so through the source than the load. It sounds like a 60hz hum. Maybe the volume pot is part of the problem too? This shield prevents outside electronic devices from interfering with your guitar’s signal and producing noise. Tracking down buzz, in-ears and recordings aside, start by turning down the house volume. The upside of noise gates is that it doesn’t affect your normal tone – they simply keep everything quiet when you want it to be quiet. The bottom side of the divider is the parallel combination of the guitar, including pickup and volume pot on one end and the amp/pedal on the other end. The NS-2 allows you to dial in the noise threshold and decay which gives you plenty of control over how much noise you filter out. How you deal with this type of noise depends on what tone you want to have. Ok, so my practice guitar amp, a Line6 Spider III 120 Watt Solid State, makes this really high-pitched whining noise when I turn it up past a certain volume. Where changing the volume also changes the level of the hum. If it does not, the the levels are not causing the issue. It’s a good option worth considering if you perform live. Hum is sound. Note gates and suppressors are commonly used when playing live to give you more control over your tone and avoid feedback, hum and buzzing. This is the natural behavior of the potentiometer and it will happen with your Tone control as well. Any man worth his salt can fix almost any problem with this stuff alone." Otherwise, take your guitar to somebody to check for you. I assumed the volume pot was bad, but I can't get it to happen again at home with the same rig. Re: Why does my guitar hum when I turn the volume down? If the humming is coming from your guitar, it will stop when you turn down the volume, because there is no longer any output at all from your guitar then. How well this would work for you depends on the quality of your guitar now. The noise also goes away when I rest my hands on my guitar's strings, but the next time I play a note, it's back.

I just wired up a friend of mine's guitar, and all seems to be well, except for the extraordinary amount of hum/crackling! 1. Noise gates like The Silencer by Electro-Harmonix work by cutting the signal when the volume lowers past a certain threshold. ! The most common cause of noise if your guitar’s volume is turned down to zero is a gain pedal or gain settings on your amp. Try a different pedal. Check the mains power in the area and if near any interference. The idea is that you can create an effects loop that you can activate and deactivate by toggling the noise gate on and off. Since you do use humbuckers and still have the issue when the volume is turned down it reduces the possibility of it being the pickups and shielding. Using a Noise Suppressor or Noise Gate Pedal, this guide for a step-by-step tutorial on how to upgrade your pickups, Fender’s Hot Noiseless Pickups for Stratocasters, Easy Upgrades and Modifications For Your Electric Guitar. But two problems: First, hum levels are comparable with my single coil guitars, i.e. The Guitar Effects Course gives you a complete overview of Noise Gates vs Noise Suppressors and how they impact your tone. One of the downsides of playing with a high gain tone is the high gain can create and amplify noise. Troubleshoot the guitar. Try a new rectifier tube. In this guide let’s look at some common questions guitarists have about hum and how to deal with it. If your guitar has a grounding problem, it’s usually due to bad soldering or a poor connection. If you buy a new guitar it’s highly unlikely you’ll experience this type of buzz, but if you buy a second hand guitar and it buzzes uncontrollably, check the wiring. Electric guitars were designed this way because it was discovered early that touching a grounded part of a guitar cuts noise. I have an AmSe Strat with Hot Noiseless pus installed. 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. Use a noise gate or noise suppressor pedal. Q: Why Does My Guitar’s Hum Get Louder When I Touch The Strings? That buzz is due to to a lack of grounding. Do you hear the hum increase when you move your guitar closer to the device? Also, running your volume lower on single coil guitars cuts down on the 60-cycle hum in the signal. When the player plucks the steel strings, they vibrate next to the magnet, producing a similar vibration in the magnet’s magnetic field, which in turn causes a varying current in the coil. Q: Why Does The Hum Stop When I Touch The Strings or Input Jack? If your guitar has this issue the ground will need to be re-soldered.

Repair ground Breakup from Bad Cable Solution: Repair or Replace Cable. Thanks so much for your thoughts on this, Jim! It is pretty linear too. Different types of pickups will result in different levels of hum or noise. I believe it might be something to do with dirty power because certain outlets are really loud while others or a bit quieter. I have had bad cables and faulty wiring in guitars do this kind of thing. Gradually increase the amp volume to your preferred level. This is explained later on and it’s a cheap option to try so worth giving a go before you try replacing the pickups entirely. The noise does go down with the volume. Really check if the amp is silent with volume down when only it is plugged into the amp. It’s either a result of the pickups you’re using, interference getting picked up by your guitar or a grounding issue. Its just the guitar now which seems to be making sound hum at like 3/8 of the volume. Plug the guitar into the amplifier and turn the volume dial on the guitar up to full. As I turn down the volume the guitar gets quitier and noise gets quieter along with it (does that make sense?). I was able to isolate the device that injected the #1 hum, where the less loud/noisy hum still exists without any inputs. This means the hum you hear depends on what’s in your home. Alternatively, you can try shielding the pickups and components as much as possible. With the volume fully opened, the ’50s wiring is identical to the modern wiring: In both versions, the tone circuit is galvanically connected to the pickup’s output, so the behavior and operation are comparable. I have shielded it with copper tape and have star-grounded it as per Guitar Nuts site instructions. This foil creates a shield around the electronics – also known as a Faraday’s Cage. That’s caused by poor shielding in the guitar, if it’s not the cables. Coming into this late.....so let me see - when the guitar is turned half way down, it starts to hum, if that wasn't bad enough it hums Rod Stewart songs? Hi. When comes to DIY home recording, especially for recording an instrument like guitar or bass by DI (Direct Input) to Audio Interface on PC, we often deal with unwanted noise, Hum and buzz.. The potentiometer (or “pot”) leaks high end frequencies to ground relative to its value. The hum is there over 90% of the time, but can be intermittent. They do basically the same thing in a charger as the power transformer does in a guitar amp. Cables can … The type of noise you’re hearing can help you figure out what the cause is. For example fluorescent lights can cause a lot of hum. Alternatively you could use a noise suppressor, but these work very differently and may or may not suit your needs. Another type of pickup uses a separat… An easy way without unscrewing the output jack is to just plug in a guitar lead (tested of course) then using the multimeter on the Ohms setting, make sure you get a reading of pretty much Zero Ohms between the tip of the guitar lead and the volume pot input(+) pin (in my case this is the left pin A). Fender’s Hot Noiseless Pickups for Stratocasters and for Telecasters are designed to give you the classic tones of single-coil pickups without the hum. I have a new hum introduced into my home theater system. The worst you can get of the unwanted noise while recording a guitar/bass on DIY build PC is the computer fan noise join the guitar sound in the recorded track.. The magic starts when you turn down the volume. Note: it’s normal for an amp to hum when a lead is plugged in but not plugged into a guitar. In most cases, the noise becomes … 2.

The below photo shows you the inside of a guitar’s cavity. Sometimes turning a device (like a desk lamp) is all it takes to reduce the hum. If so, that means you should turn your attention to your pedals or amp. Soldering the components together is a cheap way to deal with hum, which is why it’s the common method used by guitar makers. I recently bought a Harmony h400a tube amp. Try using a different gain pedal and see whether you can achieve the same level of distortion without the noise. I also plugged the guitar into another amp and there is no problem. Some pedals and amps are noisier than others. Hearing hissing, hum or any low level noise is common when the gain is turned up on a pedal or the amp. But if you’ve tried other options to get rid of hum with no luck, it’s a fairly cheap option to try. A simple test for monitors is asking a musician to … Ashcat's correct. One of the most popular noise suppressors available is the BOSS NS-2. When I turn the volume down, the noise goes down, but then I can't be heard because the volume is so low. The noise/hum usually comes in through a capacitive divider, with the random capacitance to the rest of the universe from the wire that goes from guitar to amp being the top side of that divider. In the below photo, you can see what it means to shield a guitar’s cavity: As you can see, the entire inside of the cavity and the backing of the pickguard is covered in copper foil. Move it towards any electrical devices that are turned on and listen to the level of hum. In real life, this usually means there is a poor solder connection to ground somewhere. 2. Finally they will overheat and shut down. The ground loop helps to reduce hum as explained earlier. 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. But to have it grounded I have to roll the tone down to 0 too, so there's problem. Then either make sure there’s contact between the foil and the metal components, or solder a wire from the ground loop to the copper foil. If you roll your guitar’s volume to zero, do you still hear a hum or noise? Make sure it creates a complete shield around the electronics. For example if you have a Telecaster (which are typically noisy), changing the pickups can make it sound less like a Telecaster. A pedal like this can also be used to control effects loops which is a nice option if you have some noisy pedals. The Amp is Completely Dead If the amp is completely silent (no speaker hum or hiss at all) then the problem can be just about anywhere in the amp but you should suspect a bad tube, blown fuse or the power supply in that order.. Let’s look at the three most common types of noise and what they mean to you: This is the most common type of hum you hear in electric guitars. You know the buzzing sound you hear when a lead is plugged into a guitar amp, but not plugged into the guitar?
