guitar producing a strange sound

Post by sami007 » Sun Aug 07, 2005 9:51 pm

my guitar suddenly started to produce a stange sound. when i pluck the 1st or 2nd string only, the 5th and 6th string will also vibrate making a teribble sound.
the sound is a little like a humming sound more similar to the sound of a sheet of metal being hit.
its like the 5th and six string are resonating at their natural frequency.
i am new to the guitar and would much appreciate it if anyone knows whats going on.

I wonder if one of the bracings inside the body has come slighty unstuck?

I'll think about it. It could just be a ghost note.

i got a similar problem when the strings were too close to the neck of the guitar because i had not ajusted them properly and they vibrated onto the metal which separates the frets (i dont remember the english word for it hehe ) check it out

the strings are not nutching the frets. i took the strings off and put the back in exactly the correct way but no difference. i think that when i pluck the string the body of the guitar is virbrating at a particular frequency that induces the 5th and 6th string to vibrate.

Buzz

Anyone know why my classical has developed a buzz all of a sudden and not all the time when it is kept in constant humidification? Buzz is on the low E. Has the saddle or nut moved?

A bracing is one of the struts of wood which support the guitar top.
If the problem isn't there all the time, then it is probably and most certainly will not be this.

Climate and humidity can certainly affect a guitar. Contraction and expansion can occur at certain conditions. My guitar has a low action and when I played it last night, it sounded thin and unresponsive.
This might account for Matt's problem of buzzing on the low E for no apparent reason.
A high action produces a fuller sound, although more effort is required to fret the strings, but it is less likely to be affected by climate.

Thinking about it more, plucking the 1st or 2nd string may cause one or more of the other strings to resonate harmonically. Again, the problem might be climatic.

check to c if the string is touching any of the 12 frets when plucking the string
