    The G string is buzzing somewhere around the first couple of frets on my new MIM Standard Strat. Everything else about the guitar is fine and no other strings are buzzing, just the G. But the buzzing from the G is driving me up the wall as fret buzz bugs the shit out of me. My tech had adjusted the action, etc. and everything was fine at that point so I am guessing that the guitar has simply settled a bit or that the new strings have stretched.

    When I place a finger behind the nut on that string the buzzing stops so I am assuming that this means that my truss rod needs just the tiniest adjustment. Problem is, I never play around with my truss rod so I am not sure in which direction to turn it in order to resolve this. Can anyone help? Actually, I'm sure damned near everyone here can so I should say - would someone mind helping?

    Sounds like a shim for the neck is in order.
    It was the only way for me to get rid of some buzz I experienced.

    To the right straightens the neck. So, to the left!

    Try raising that string in its nut slot, with a small strip of 3x5 card or the like. Then try two strips, etc.

    I made my R8 the most playable guitar in the world by doing that and, months later, got around to doing the job "right" with Super Glue.

    Look at the neck from the headstock down to the body and see if you have some relief in the neck.Do this from the body back up the neck and see as well.Strats need just a bit of relief or up bow.
    Take a pic from both ways and post it here maybe we can help.
    Being only one string is doing this maybe just fill the nut slot and re file.

    I agree with each previous post.

    Here is my take on it:

    I like my Strats low and straight. So, I get the buzzy, snappy Strat flavor in my tone. However, you can have too much of a good thing.

    If you add more relief, by loosening the trussrod, your action will go up. You may like this. If not, you will have to lower your saddles.

    If you shim the neck pocket, thus raising the headstock, same effect.

    Your problem is most likely as River has suggested. The "G" slot in the nut may be too deep. I have had this problem too. You should try Riv's suggestion first, since it won't require any other neck/bridge adjustments. If it works, you know what you need to have done.

    For the record, the truss rod nut works like all other nuts/screws: Righty Tighty, lefty loosey, If your truss rod screw is at the neck heel.

    Tightening the trussrod nut takes the relief out and flattens the neck. Loosening the neck adds relief and bows the neck. You can go too far either way, and I suggest loosening the strings before you adjust.

    Good Luck!!!

    As far as the question which way, from the headstock looking down the neck turn to the right to get the neck flatter, to the left to get relief.

    Col, do what Riv said. :thumb:

    I take it your Strat has only one string tree, for the high E and B strings?

    I'll find something to put in there.


    Yes. I was thinking earlier that another string tree would solve this perfectly (based on it stopping when I touch the string behind the nut).

    You could do that too.

    I'll also post pictures here after the batteries for my camera have recharged a bit.

    If it's not the frets buzzing It sounds like the nut slot in not cut correct, it's either too wide or the angle of the cut is wrong. Before you do anything like filling or cutting the nut, add some ky jelly to the slot, that may result in temporarily stopping it, next time you change the strings you can also try winding as much string as you can on the tuner.

    If none of that works it's time to look at the slot.

    I was in the store for something else this afternoon and I spoke to my tech. He suggested that, because it stops when I press the string behind the nut, I could just add another string tree. He also mentioned adding extra winds around the post. He had some string trees there so I just grabbed one of those and will put it on later tonight.

    Well worth a shot, but remember that when you press on the string up there, you're putting extra tension on the whole string, sharpening it. The tree may have little or no effect with your gauge of string tuned to standard pitch.

    I'm using .09s and figured I would have to adjust the intonation after retuning. There is also a spacer with this string tree so it isn't cranking it right down or anything, just putting some pressure on it.

    I'll take the guitar in to him tomorrow to let him see it and determine that he definitely thinks it is the way to go. I'll also have him look at the nut while he has it. If he still thinks it is the way to go then we can install it while I am there.

    Good idea to let the tech look it over.

    Riv is right again.

    If you stop the buzz by pressing down the string behind the nut, you are raising the tension, and the note. When you release the tension back to normal for the note, it may still buzz.

    Even with a new tree.

    River should be a Tech.

    It doesn't sound like a truss-rod issue, to me. I think Riv and Nigel are right to suspect the nut slot. If that isn't it, you might have a hinky fret in there somewhere.

    But yeah, lefty-loosey righty-tighty, as mentioned.
