E, A, and D buzzing

I just got a new guitar the other day, its a Fender Strat, and I played it for about 2 hours when it arrived and it sounded great. Then, i left to go somewhere, and when i came back i noticed the E, A, and D strings are buzzing. They buzz when i dont hold them down, and when i do hold them down. Any idea on whats happened? :confused:

it is probably the wood taking in water and expanding. This can change the guitar setup and is not too difficult to fix.

I've tried adjusting the action (i think i was doing it right. I was turning the screws on the bridge at the end of each string clock-wise), and it helped a little bit, but it still buzzes a lot. And Im not sure how to adjust the truss rod.

i have the exact same problem, E,A,D with buzz. I adjuted everything including the rod to factory settings but still the buzz remains :confused:

Are you tuning to A440 ? Going up a gauge in strings may also help.

If none of that works it may be time to get a professional to look at it !

I read this in a book about guitars. It works for me. Start with every thing in tune. Then put left first finger on #1 fret and right thumb on #15 fret. Take right middle finger to fret #7 you should have .015 or 1/64 inch.between string and #7 fret. If too much tighten truss 1/4 turn to the clock wise. If distance is less than 1/64 loosen truss counter clockwise 1/4 turn and check again. Then lower untill you buzz and back off untill you don't buzz. As for E,A,D, they need a little more distance then the other strings because they move more with respect to the higher strings.

A number of things could cause this to happen...

1. Your strings stretched while they were under tension. You would be able to tell if this happened because they would have been out of tune.

2. Your neck was exposed to a change in humidity while you were gone and warped just slightly. This usually takes a day or two though since hard maple isn't a very plyable wood. Also, I don't think this is the case because the guitar is brand new and this normally happens to guitar necks that aren't lacquered. Fender puts some type of finish on all it's neck to protect it from this type of warping.

3. The guitar is brand spankin new and the truss rod shifted a few milimeters due to the string tension. This is rare, but sometimes when a truss rod is fitted it won't be totally locked down. Then after it's under a load for awhile it will finally shift into place. The guitar would sound out of tune for this as well.

Things to counteract this. You were in the right to adjust the action if the strings are buzzing... however... you were doing it the wrong way. You can adjust action from the truss rod, or from the bridge. You chose the bridge, which is okay and probably the proper place to start since your strings are buzzing even when they're open. You started by turning the screws at the end of the strings (philips screws) these screws are for adjusting intonation... not action. The scews to adjust string action are the hex screws on the bridge saddles. These are the screws you should have turned. As far as adjusting the action from the truss rod... you can use the procedures above. If you don't feel comfortable with any of these procedures, or don't know what we're talking about... just take it to a tech man... You might have already messed up the intonation. So I suggest taking it to someone who can fix you up.

Thanks everyone. :D
I adjusted the pickups a little bit which stopped the buzzing on the open EAD strings. Then, i adjusted the action from the bridge, thanks to aschleman for correcting me, and that stopped a lot of the fret buzz.
I also read some stuff on how to fix the inotation that i had screwed up :p and so thats fixed as well. Thanks for all your help!
