Acoustic guitar resonance

I've got my guitar ( Washburn d10sb bk ) freshened up with new strings and got it tuned correctly.
I keep hearing dominant tones.

I thought it might has something to do with the acoustic treatment but no matter where I strum the guitar, I keep hearing these dominant tones. ( Especially in recordings )

For example, if I strum the Asus2 chord back and forth, I can hear a dominant tone and a frequency analyzer comfirms it @ 987.77Hz
I used to EQ these dominant frequencies ( which was truly a pain in the.. ) with my old recordings, but I want it to be recorded as good as I can get because it also cuts aways some good sounds.

The "B" ( And pehaps E ) Strings seems to cause most of these problems.

Thank you! :)

-NOTE-
Since I'm new here I already posted this on the "Newbies" forum.
I got redirected by miroslav to specificaly "ask Muttley" for help concerning this matter.
 
Mutt is in England so it may be tomorrow before he looks in again. Or Monday.

Impossible to say without hearing a sound clip. Sorry.

Are these "dominant tones" dissonant or just an unbalanced or dominant frequency? Are they ghost tones (higher notes of the same pitch). Is it audible when played acoustically?

A sound clip and some more info would help.
 
Sounded like something "hollow" came in at :10. Higher pitch.

I'm not a guitarist, but I have to do this anyway, so please try not to pay any attention to errors I made in this clip. ;)
It's like a harmonic-ish sound that is dominating the others, usually somewhere around 1 kHz.

If I look at at the file with a fequency analyzer, I can clearly make out the problem.
I don't think it's quite noticable on laptop speakers.

I've amped the problem frequency a bit, you should be able to hear it now.

Ok you need to take a methodical approach to this and do some takes on single string notes. Find out which string and then if it is happening on all frets on that string. Start with the high e and when you find it post details.

Good luck.
 
Heard nothing when I hit one string at a time but... ( always the )
If I strum "all open" and damp "high E" and "B" Solo or Together, the tone seems to dissapear.
If I use the frets, I don't hear it as obvious then when it's open.
 
This guitar was just a plain Washburn guitar.
I'm a lefty so they've modified the guitar correctly and build in a pickup.
They also gave it high quality elixir strings, that was somewhere in 2009.

A few days ago I've replaced the strings ( it was about time, too ) they've tightened or loosen some things ( im not sure exactly what )
It sounds a little better ( I've got the same high quality strings ) But the strings tend to buzz when I play them ( probably because they're new, I think I had that problem when I first got the guitar )
But over time it was gone and played good ( exept for that tone )

Thanks for your advice.
 
Can you hear this tone "live" when you are playing or is it only during playback of the recording?

Both, it's not the monitors.

EQing helps but also ruins the sound a bit.
If I were to play another chord, it tends to go a pich higher.

EQing all of these dominant tones really ruins the natural resonance of the guitar.
 
I wasn't thinking monitors, I was thinking the mic/pickup system. I've never heard a resonance like that before. It's like you've got a ghost in there. That is very strange. I'm not gonna be any help on this one. Sorry.

My guitar has been modified by a well known builder ( Zwier, Netherlands )
The man is also known for proving right handed guitar can be made left handed without certain problems.

It's not my dream guitar, but it does get the job done.
 
Remember that I've amped the recording in the last link ;)
I've kind of solved the problem by damping the strings above the nut which was apparently causing some weird resonance.
I can still hear it a little, but not as loud, I can live with that. I hate over-EQing my guitar.

Then again, this kind of problem is to be expected with a budget guitar.
Thank you all for your help. :)

-Edit- Remember that the problem is not yet "fully" solved, so any suggestion will be appreciated.
Apparently both "High E" and "B" is causing this weird resonance.
