Why is there a murmur when the guitar is empty?

There are basically two reasons for this:

1.Your pickups are single-coiled, humbucker has a phase-canceling effect, so there will be no noise, while single-coil timers don't, so there will be noise, especially if you use a poor quality guitar wire or too much ambient electromagnetic interference.

2.Your pickup circuit is not grounded properly, generally the pickup ground will be connected to the metal casing of the volume or tone knob, or you will put a graphite layer on the wood of the guitar and lock the ground directly on the surface with the graphite layer, and you will also have the ground wire connected to the base of the rocker.

If none of the above two are true, then you have a problem with the pickups, go back to the piano store where you bought the piano, and ask them to help you deal with it, as for how to deal with it, I won't go into detail here!

Hope it helps

It's a few strings. Generally, it may be a hit.

Find the place where you hit the product and wrap it in a cloth.

Just hit it in with a glue hammer.

Don't be too pushy.

It was easy to hit hard.

It may be a problem with the power quality of the connected effect (try to try the battery), or it may be the surrounding electromagnetic field, if there are high-power electrical appliances around it, it may also be a shielding problem of the line, (change a better shield wire to see), and the noise disappears when pressed by hand, because the induced current generates a loop.

Let's play the product, you can tune it, find a piano shop, they have the tools, just tune it.

Addendum: It should be a hit, do you have a capos? If you have one, try to clip on the capos!

Playing products, I also had this kind of problem when I was in the past, find a piano shop, I can help you repair it, it is best where you buy it, where you repair it, maybe it can be free Hehe.

Summary. The reason why the guitar has a murmur and many times pops up the murmur is that your basic skills are not solid. The basic skill is that the finger strength of pressing the string is not enough, and it is not accurate.

If the strength is not enough, if you don't press the string tightly, the sound will split. Inaccurate pressing means that when your finger presses the string, it does not exactly press the string with the center of the finger, and it is up or down, causing the finger belly to touch the next string and produce noise. In addition, when the finger cannot be opened, one of the fingers presses the upper part of the metal product, causing the sound to pop up and make a noise.

The correct way to press is to hold the string in the center of the belly, in the upper third of the metal product, so that the sound played is full and good, as long as you can press the string according to this standard, you can eliminate the noise.

In addition, after pressing a string with the left hand, it should be lifted and not too close to the string, which will cause the finger to touch the empty string and produce noise, and then the right hand will touch the vibrating string when it is silenced or played, resulting in noise. With constant practice and attention to detail, you can play a clean and full tone.

Sometimes the occasional poor quality of the copper coating of the strings from the factory bezel can also cause noise, and this can also be the case with new strings.

Summary. Solution:

1. The strings collide with the strings: because the string shaft hole is too close to the first line, the two strings are close, and they will rub against each other and sizzle when vibrating. Processing:

Use a screwdriver to split the two strings that rub against each other, and use a screwdriver to split the strings from above the string pillows, and stumble between the strings to separate the strings.

2. There are debris between the strings: there are debris between the strings or between the strings and the horse, and these debris will be encountered when the strings vibrate.

3. The strings rub against the strings: if the strings are not pressed tightly, the chords will rub against each other to produce noise, and the strings can be judged if the noise disappears with a screwdriver above the string pillow. Treatment: Tighten the chord screws.

4. The strings rub against the string screws: If the strings are too close to the strings, the strings will also rub against each other when vibrating, resulting in noise. Handling: A cloth can be padded between the strings and the string screws.

5. The strings rub against the other string nails: if the string nails are loose or the position is not right, the strings cannot be effectively pinned, and the noise will be generated. Treatment: Pin the pin or correct the position.

Solution: 1. The strings and the strings collide: because the pinshaft hole is too close to the first line, the two strings are close, and they will rub against each other to make a sizzling sound when vibrating.

Treatment: Use a screwdriver to split the two strings that rub against each other, and use a screwdriver to split the strings that are difficult to split from above the string pillows, and trip the strings between the strings to separate the strings. 2. There are debris between the strings:

There is debris between the strings or between the strings and the horse, and when the strings vibrate, these debris will make a "sizzle" sound, treatment: clean up these debris. 3. The strings rub against the strings

If the string is not pressed tightly, the chord will rub against each other to produce noise, and the string can be judged if the noise disappears if the string is pressed against the top of the string pillow with a screwdriver. Treatment: Tighten the chord screws.

4. The strings rub against the string screws: If the strings are too close to the strings, the strings will also rub against each other when vibrating, resulting in noise. Processing:

You can put a cloth between the strings and the string screws. 5. The strings rub against the other string nails: if the string nails are loose or the position is not right, the strings cannot be effectively pinned, and the noise will be generated.

Treatment: Pin the pin or correct the position.

Look at whether the string spacing is too low, and don't turn the volume up too much, and then check whether your hand is tightened? (or capos) the rest may be a problem with the speaker.

You look at the taste of the piano.

Is there a phenomenon of hitting the frets close to the 12 strings?

The noise may be caused by the hitting.

In the case of an electroacoustic organ, it may also be a problem with the pickups.

In the case of low-grade pianos, it may be that the neck does not meet the requirements and causes problems such as playing the product.

There are several situations, one is that the front baffle of the headstock at the string button is not pressed and loose, the second is that the gong wire of the string button is loose, the third is that the copper wire of the outer ring of the string is worn and broken into a section, and the fourth is the gong wire of the string neck. (The speaker hole is near the neck) the fifth is that the sound beam in the speaker is loose, and the sixth is the loose gong wire that fixes the bridge wood under the string bridge (the string part of the piano case). Seven is to play the product, eight is the string cushion (headstock string strip) string groove mold width, you can pad some paper to try.

The left hand is not tight; 2. The quality of the guitar is not good, and the strings are beaten; 3. Some parts of the resonance box are not firmly bonded or have cracks, and such problems will also occur. The first problem is easy to solve, as long as you usually practice more horizontal press (to press the position), the last two problems are the quality of the guitar, if you play the product, file the high product with a file (be careful), the latter problem is not easy to do, it is recommended that you change to a better guitar, the poor quality of the guitar hurts the hand, the timbre is not pure, and it is not good for your playing and hearing.

Come to say! I just want to ask the landlord a few questions. Did you pass the parlay?

Don't make the price of cabbage! DIY yourself! The key question is what does the guitar look like?

If it's a piano at the price of cabbage... Just bear with it! It's all like that!

It's normal for hundreds of pianos to have noises! Because it's cheap! More than 2000** there is no noise!

The line is not a big problem, as long as you don't go into the recording studio for dozens of lines! Not to mention that your positioning is too bottom. It's time for a good piano!

If you're sure there's nothing loose in the piano, try changing the strings.

Press the string tightly, the tip is to press the position close to the right side of the fret, it is easier to press tightly, and pay attention to the palm of the hand when pressing the top three strings, whether the palm accidentally touches the lower string, and sweep the string with a fingernail.

If it's not one of these problems, it could be a problem with your guitar amp.

You can copy it for sure that this is the problem of the piano, is it always felt that the headstock has a slight hum, the more carefully you listen to the more obvious, you are still good, the first piano I just bought, 34 strings have a similar situation, this is because you 2 tones and the headstock resonate, play other notes are not right, it doesn't matter, as a practice piano may have such a small problem, don't care too much.

If you really can't come, buy a good piano, brother.

Acoustic guitar, you play with a stereo, right?

Reason for noise 1 The strings are loose, that is, the strings of the headstock are twisted There is a problem, A2 There is a problem with the pillows on both sides 3 There is a problem with the bridge. 4 Strings and frets have problems with whether or not to hit the frets. 5 Is your string broken, the 3 strings of the acoustic guitar are all wrapped, is the copper wire broken, and it falls off, 6 Is the sticker of your guitar loose or falling off, the guitar makes sound by vibration, and if it is loose, it will vibrate, and if it vibrates, it will have a sound.

7 about whether it's your audio then I don't know.,Audio, you can change the pronunciation source to try the audio.,Generally I think the audio should be fine.。 Unless your stereo is rubbish.

If none of the above are the same. Then it depends on the problem of playing the guitar, if you use the stereo, there will be a certain reverberation when the two strings are played at the same time, and it will sound like a murmur, and if you play only one string, he will not have it, and this is a technical problem, and you don't know where your murmur comes from, so you can't find someone who understands it to show you.

Is the problem solved? Mine is the same, so the strings only need to play the two notes of 7 1 in the key of C, and the guitar will not be played lying down, and it will be played when it is picked up, which is annoying?

Just now, I was like you, the screw on the headstock knob was loose, dizzy

Have you found the reason I also have this problem Can you tell me if there is a solution? Thank you.

Oh, if the position is pressed correctly, and in place, that's the reason for your guitar, the string spacing is too low, causing the string to collide abnormally with the frets or finger wrench, making the piano make a sound similar to clicking. The phenomenon of hitting frets is a very common problem in guitars.

Adjust the order, hit the copper, raise the bridge, adjust the fretboard rebar, and toss the pillow! For low-grade pianos, the frets are generally cocked on one or both sides of the fret, which can be improved by knocking on the frets and raising the piano finger bridge! Use a plastic hammer to make the tall frets a little shorter!

When adjusting the steel bar, pay attention to the same principle as the general screw: the counter-clock is loose, and the clock-forward is tight.

The internal steel structure of the neck is that when it is loose, the neck will be tightened by the strings, that is, it will be bent towards the front of the guitar. When tightened, the steel bar will pull against the strings, and the tighter it turns, the more it will bend towards the back of the body.

In addition, check whether the guitar is a standard tone, and some guitars will also play if they are not standard tones.

The above method is better to find a professional who is related to the person to rectify, once it has been done, the piano may have to be replaced, or it is more appropriate to go to the piano shop.
