About 3 months ago I bought an Ibanez RG652FX. A few days ago I noticed a weird vibrating sound when I played a hammer-on on a G string. It is most noticeable when playing 9th to 11th fret hammer-on but it also happens on other adjacent frets in that area and I can hear it to some extent on D and B string as well. It also happens when sliding. It happens when playing distorted and it is not noticeable when playing clean.
At first, I thought that the pickups were too high so I lowered them as much as possible but there was no difference. I replaced the strings but the effect remains.
Then I noticed that the effect goes away if I mute the lower strings (E, A and D when playing G).
Here is the recording of a hammer-on G string 9th to 11th: https://soundcloud.com/martin-volk-20676163/hammer-on-vibrating/s-XV2Fli25SbZ
And here is the same while muting the lower strings: https://soundcloud.com/martin-volk-20676163/hammer-on-muted/s-mUQrbcDbzGv
It seems like playing certain notes is causing some strings to resonate. I haven't played guitar for a few years so I'm not sure if this is normal behavior. I don't remember having this issue with other guitars I played.
Is this a normal behavior and I just need to always mute other strings to prevent it or could this be an issue with the setup?
