High E resonates like a sitar

[lafromla1]

I've had a problem lately with my VIP where when I hit an open high E, it resonates like a sitar.  No other string does this and it does not do this when the string is depressed at any fret, only when hit open.  I've changed strings and I am still getting the same sound.  I thought maybe its vibrating off of the first fret, so I raised the saddle...same sound.  I checked the relief on the neck with a straight edge and every fret seems to be flush to the edge, so I am thinking that a truss rod adjustment may be in order to give it a little bow?  Any other ideas on what would that cause this sound?  It's only happened over the last 4 weeks and I've had the guitar for approximately 2 years.

Some specs:
Wilke trem
Graph Tech Blk Nut

TIA

The nut slot for that string is wonky.

The nut slot for that string is wonky.

Even though it never made that sound before?

I gave the truss rod a quarter turn and re-tuned the strings.  Sounds better, but I will check again tomorrow evening after it had some time to adjust.

If adjusting the truss doesn't help, then I'll have the nut rechecked.

Yes. pretty much most of your weird problems with tuning and funky sounds are going to be your nut - only look at other stuff if you are sure it's NOT your nut.

I had a nut that cracked on a solitary string and it sounded like that.  took me a while to pin down why, but a nut change later it sounded pristine again.

I'll check for a crack or any other weirdness when I get home.  I sure hope that isn't the issue.  I read somewhere that it could be from the slot not being cut deep enough, but I dont see that being the problem.

Most likely you'll just need a whole new nut, if it's split under the string or it has worn in a funny way (too wide at the string exit point, most likely). You could try filling it and whatnot, or just get a preshaped nut from Mojo or somewheres and file it / have it filed.

I'll put in my vote for a gimpy nut, as long as we're making a pile. Don't forget to have the guy who puts on your new nut adjust the truss back to where it belongs.
