Thread: Picking string causing other string to make noise

Please help!
My electric guitar is making weird noises.

Whenever I fret the 10th fret on the A string and pick it, the G string on my guitar slightly vibrates as well and makes annoying background noise (almost as if I picked the 10th fret A string then lightly picked the G string simultaneously) when going through distortion. I've noticed this happens in other areas on the fretboard too with different strings slightly vibrating other strings not adjacent to it, but the 10th fret A string has been the worst and not even my noise gate is taking the sound away.

I have no clue what could be causing this problem. I've also noticed that my intonation is off slightly, when i move up the fret board the notes get flatter.

Can anyone help me with this problem!? It has frustrated me to no end!

What type of guitar do you have...sounds like you need to raise the action...intonate...and possibly adjust the truss rod.

Action adjustment

To intonate a guitar you need to adjust the saddles of the strings that are out.

Its a Jackson Dxmgt Dinky. I intonated by adjusting the saddle bridge and still the same problem. Tried raising the action, still no luck. The only other thing from what u said is the truss rod, and i'll give the a try. Someone told me to fix this problem i need to 'dress the frets', is there truth to this?


Guitar101 - 7/30/2006 at 00:06

Does the buzz start low then get louder with a high pitch sound?


Spidercents - 7/30/2006 at 05:03

How old is the guitar?...are there little "notches" worn in the frets from the strings...fret dressing and or replacement might be the answer.

Im not saying to do these things below...these are the possible problems you may have and how to fix them once you hav figured out what it is.

--------------

To dress your frets: you will need to adjust your neck as straight as you can get it. Then it's a matter of levelling the frets with some type of flat, straight abrasive surface. There are as many methods used as there are repair people! Some use a good file, others use glass with sandpaper attached to it, and some use a good woodworkers' level with sandpaper glued to it. To simply describe the process, you use this tool to sand down the tops of the frets, taking only the minumum amount needed to make ALL of the fret tops the same hieght. Then the frets are re-crowned using the fret crowning file and polished to a mirror-smooth surface to make playing and note-bending an absolute joy!

Fret-dressing can be a pretty involved process, so read up on all that you can before you jump in. Get the right tools and maybe even practice on a cheapie or two before you try it on your Les Paul.
---------------

Check the nut...is it cracked...are the grooves cut to deep...are they cut sloppy...replace it with something other than plastic if need be.

---------------

If the first notes played on any string are clear, then you get to a fret that buzzes: you need to see if each fret after that one buzzes as you progress up the neck. If each fret buzzes, you have a neck angle problem. If only that one fret buzzes, it may be a high fret.

----------------

To check for a high fret: use the short straightedge and set it across three frets. If it rocks at all, then you have a high spot. Check up and down the entire neck this way. You can use a fret crowning file to lower a high fret but be very careful and make sure you've diagnosed the problem correctly because if you file down a fret that was not really too high, or if you file down a high fret too far, you will be creating a buzz on the next fret. You just made a fret too low and now you will need to dress the WHOLE fretboard!

Guitar101- yes, well the noise seems to at first blend with my picking of the 10th fret A string, and then when i mute the A string the open G still makes this annoying, higher pitched noise.

I've found out that this is occuring all over the fretboard, in the A string and D string mainly. I am getting sympathetic tones, as long as the note corresponds to an open string, that open string will make a noise, some more annoying then others. I've also noticed that if i dont touch the strings and am by my amp, my G string will start to make a very high pitched tone noise until i mute it. I know that sympathetic tones happen often with guitars but on mine they just seem blown out of proportion. Maybe its my setup? Still no clue

Spidercents- my guitar is brand new, so i dont know if i need a fret dress, but if all else fails who knows
The nut you're referring to, is this the nut on the truss rod?


Spidercents - 7/30/2006 at 16:38

I had a guitar where the nut was cracked and caused buzzing problems.



I actually think the problem may be a high fret...thats what it sounds like however I never had this particular problem before.

Spidercents - 7/30/2006 at 16:57

I actually had a buzzing problem recently and had to raise action and adjusted truss rod and it fixed the problem.

Are there any loose gear parts...check and see if anything is loose.

More info about where a buzz might be coming from...lots of good info.

A loose nut on any of your tuning machines will cause all kinds of noise.


cyberpunk409 - 8/10/2006 at 06:23

guys, i'm suprised and disappointed that no one has been able to pin point the reason for pirateabc's problem.

pirateabc, when you play the A string at the 10th fret, what note is that? It's a G... Certain notes set off resonant frequencies within the wood of the guitar. As you play the A string 10th fret the wood starts to resonate with a certain frequency, which just so happens to be the IDEAL frequency to start the g string vibrating... hence the G sounds like its played. It happens across other areas of the neck, other strings and at different frets for the same reason... if you play the G string at the 9th position (E note) you may notice the both high and low E-strings vibrating...

To overcome this, you gotta learn to play and at the same time mute strings that you don't want vibrating... takes a LOT of practise, i'm still trying to perfect it.

As for notes playing sharpy/flatly... well yes, it MAY have to do with intonation... but understand that even with a perfectly intonated guitar at the 12th fret, you're still gonna get flat and sharp notes across the fretboard, such is the nature of guitars.

You can try the buzz feinten (sp?) system or something similar, but they are costly mods to make. If you wanna play guitar, you gotta accept it's curse... perfect intonation is near impossible.

Y'know i joined this board JUST to answer your question... hope it's appreciated

Also if your heavy handed or just plain have bad technique you will push the strings down sharp or flat. If you tone deaf then you don't have a chance Practice with a tuner. Hold down the strings on the upper frets and see what the tuner tells you.


We didn't want to insult pirateabc
as muting is very beginner


Common sense just aint that common


cyberpunk409 - 8/11/2006 at 01:08

no, i'm not talking about muting in the typical sense... we ALL know how to palm mute... that IS very beginner...

i'm talking about if you're playing a solo on the upper frets (i.e. slash style) and you're playing on the B and G strings then learning how to mute the E A D and high e strings whilst letting the B and G ring out is difficult.

When i say "mute" i don't mean chuga chuga chuga chuga sort of mute, i mean SILENCE... stopping the strings you're NOT playing from making a sound.


brian - 8/11/2006 at 03:21

mute,silence,deaden.. pretty much the same!


tattoo - 8/11/2006 at 07:01

My point exactly


cyberpunk409 - 8/11/2006 at 07:32

yeah, well in guitar talk muting can mean two things...
1. muting a string by gently resting your palm on it and playing that particular string on purpose to get a 'thump' sorta sound out of the amp, OR
2. muting a string to stop it from vibrating accidently, hence stopping that particular string from being heard at all through the amp.

in this thread, the guy is hearing strings through his amp because he isn't doing type 2 muting.

you guys like to overcomplicate things in this thread...

buddy, there's nothing wrong with your nut, bridge, frets, etc etc... the noise you're hearing from your G string when you play the A string, 10th fret is normal to your guitar. It's to do with the wood, etc.

don't go wasting your money on a tech


Spidercents - 8/11/2006 at 17:49


It is normal for the G to slightly sound or vibrate when you play the 10th fret on the A string however the guy also said the guitar is making weird noises and annoying background noises...if it was just the G string sounding out it wouldnt make weird noises.

The best method is to have the guitar in your hands to really get down to the problem.


drk529 - 1/11/2007 at 03:40

sorry if someone said this already, but...

notice how 10th fret A string is a G... the harmonic properties are what cause this, and it happens on most guitars.

Edit: just saw your post, cyberpunk409...

brian - 1/11/2007 at 04:23

very unlikey to cause weird sounds it's most likley a high fret, cracked nut, trem strings vibrating etc....

i just reread the first post, and it seems as if his only reference of a "weird sound" was saying an annoying background noise, which is probably one and the same as the g string vibrating. Anything weird about it was probably caused by the distortion. the only thing you said that could likely be part of his problem is vibrating trem springs... this is a sonic issue, not a guitar issue like a high fret or cracked nut.


Guitar101 - 1/11/2007 at 21:05

The only real way to find out is to have the guitar in front of us.
