OK,so here's the deal, I own a Jackson KE3 Kelly and I recently noticed that when I play the 3rd fret on the 4th string, the 8th fret on the 5th string and the 13th fret on the 6th string the real note sounds on a very low volume and everything I hear is an extreme vibration.I can't even pull out pinch harmonics there.
The guitar has a Floyd Rose trem if it helps.
Could it be the note itself?
Here a link on the guitar:
Hmm... Sounds like an action problem. If it's on that many strings, it might be fixable via truss rod adjustment. Take it into your local guitar shop and tell them your action's a little low, and ask them how much they'll charge you to "set it up."
