I've been having some trouble with buzzing beyond the 12th fret on my Am Dx strat.When I raise the bridje the buzz stops but then the action is a bit too high.The neck is pretty much straight with a slight bow.Do you guys think the neck can be tlted a bit to help with the buzz ?There is a tilt adjustment behind the neck (something to do with shimming I guess).Will it help adjusting this area?

Loosen the nut to add a small amout of relief.

You need to undo the micro tilt. It sounds like the neck is too parallel to the body.

If you use the micro tilt make sure you lossen the screws by 5 turns before doing so and only turn the adjustment a 1/4 turn at a time I believe they say a full turn is equal to 1/8 action.

That drastic eh Cvillera? They should of called it mega tilt eh? I think the OP has too little tilt which is leading the headstock being too much towards the back of the guitar. It sounds like it needs to move more to the front of the guitar. Or if you lay the guitar flat on a table, the back of the headstock would sit too near the tabletop and needs to move up slightly.
Still the advice of caution is always good advice.

That micro tilt sure does not take much to get it moved. I amazed at how I have been told people try to use it without loosening the screws first but I agree with you on the move. A lot of people don't no that the first 7 to 9 frets along the neck from the body should be straight then the relief comes into it but that straight part has to be right with the body.

Sorry.Not sure how to do the quote thing!Please check the previous message.

I believe he means the truss rod nut.

Having tried all I think I am going to work on the micro tilt.So I presume,from what you guys say,that loosening the micro tilt will bring the headstock in front.Just a couple of questions on it :
I guess I need to loosen the screws before doing this.Does this mean that after doing the micro tilt job I would need to tighten the screws exactly where it was or do I need to tighten the screw at all.(This may be a bit of a dumb question,but I would rather make sure.)
IS there a link with more info on the micro tilt you can post here?
Thanks

Here's a quote from the support section:

For guitars with the Micro-Tilt adjustment, loosen the two neck screws on both sides of the adjustment access hole on the neckplate by at least four full turns. Tightening the hex adjustment screw with an 1/8" hex wrench approximately 1/4 turn will allow you to raise the action approximately 1/32". Re-tighten the neck screws when the adjustment is complete. The pitch of the neck on your guitar has been preset at the factory and in most cases will not need to be adjusted.

The above mentions tightening the micro tilt.Is it okay to loosen.I guess by tightening it would raise the hell of neck which I won't need as there is already a buzz problem there.

Ok JC here goes.
What you need to do is move the headstock so if the guitar was laid flat on a table the headstock would be higher than where it would naturally be. Infact lay the guitar flat on a table and measure between the tabletop and the back of the headstock.
Check the neckplate of your guitar there should be 4 screws that secure the neck to the body and a hole inbetween 2 of the screws that takes either a allenkey or screwdriver. (thats where i get blurry) dutune all the strings so there is no tension in them and loosen the screws securing the neck. Now adjust the micro tilt adjuster a tiny bit so that the measurement between the headstock and tabletop increases by 1 or 2 mm (clockwise i think but like i said i'm hazy). I believe that american standards come with the neck set without any tilt, but i dont know why its been years since i last saw a microtilt.
When you think you've got it right re-tighten the neck securing screws, check your measurement again to make sure. Retune, change the string heights, play the guitar for a bit to check youve solved the problem and re-intonate.

Thanks niki.Cloclwise or anti clockwise,right or left turn,that is the question ! I wish you wouldn't be hazy today (lol ).Anyway the headstock height measurement may help.Thanks.

JC you will be quite safe aslong as you dont force anything and make sure the neck screws are loose. Infact why not take the neck off and give the microtilt mechanism a closer inspection so you understand it more. Remember CVilleira's advice though. A small adjustment makes for a big change. Thats true of nearly everything with necks.
