Ok so today I restrung my Floyd for the first time (dun dun). I had D'addario heavy bottoms before (10, 13, 17, 30, 42, 52 ) and the guitar was set up for this gauge. Everything sounded good, I only had buzz on the G string (not enough to bother when amplified) and the rest played great.
Now today I restrung it, and it's tuned. I didn't lock the nut yet, it's just resting. Tomorrow I will intonate it (er... try... I've only kinda just started guitar. About 3 months ago) and see if I have to raise the action. But can you guys give me tips already? Right now the G string buzzes when played open, on the frets. The others don't (unless of course I slam them). When fretting though I get quite a lot of buzz that I did NOT get before. I don't really understand that. Right now I'm using Ernie Ball Slinkytop Heavy bottom (exact same gauges as before).
Help would be appreciated... Thanks!
Edit: I just locked the nut and played a few chords. It's still buzzing, even over the distorsion and amplified sound.

Check the truss rod.
Also measure at the first fret,it should be about 1/32quot; above the fret for each string.

I work with millimeters, I have no rulers or scale accurate enough to give me this kind of measurements
But yeah I just considered turning the truss rod a quarter of a turn to the left (loosening it). This way I'd get a bit more relief and I doubt it'd harm the guitar.

Use a piece of the string that you've clipped as a gauge.I think something close to .045 should be good.Slide it under each string at the first fret.Even if the string catches it should still have a lot of play.I'm geussing that the piece will hold snug at the G string.

Should I use the .42 (my A string) ?

Ya,try that.

There's no room for the string to pass on all frets. But this fret doesn't buzz at all though. And my action has always been very low without problems before
At the moment my action is a bit less than 3 millimeters on the 12th fret.

Are all of the strings at an equal height on the first fret?
It sounds like something isn't lined up properly.If it just started buzzing with the string change,then you may have overlooked something.
I wonder if it's not fret buzz but something may be loose.Double check everything to make sure it's snug.The noise could be a vibration,check this by just lightly pressing on all of the parts that affect the G string.

Well the problem isn't this... The G string has always buzzed when open but never bothered me because it wasn't hearable whem amplified.
But even when amplified I can hear buzzing on the whole of the neck now

I think you should take it to a tech for a once over.I'm willing to bet it's a small,(but annoying),problem.

I guess so too.
I got this guitar in mid February and I had it checked (the trem knife edges were worn out, it needed a fret job and new strings). The tech said that it couldn't take .10s so he put .09s again (...) and the guitar buzzed quite a lot. Then in Amsterdam (where my parents live, I am in Edinburgh) I got it set up again for .10s, and the tech but those heavy bottom (which by the way feel awesome) and the buzz was all gone except for the G string but it never bothered me.

Ok so I got the allen key I need... Should I raise the posts with the Floyd still on, or take it off first (which means another hour of work and knife edges worning out )?
Please I would like to do it today... As soon as possible...

Ok meh I just raised the action (by a millimeter or so, and I didn't take the trem off) and well it didn't help at all... All strings still buzz when fretted.

Well, it seems that your new strings are lower tension than the stock ones! Are your floyd aligned straigth with the body of the guitar (excuse my bad english ), or does it have an angle? Try adding a spring to the floyd and\or tigthen\loosen the tension so that it goes straigth .

I've had the same problem before, but adjusting the spring tension of the floyd fixed it.

Hope this helps,

Measure from the top of the body to the top of the fret board,(but not the frets),where the neck joins the bosy and take a similar measurement at the end of the fretboard.If the neck join measure ment is lower than the end of the neck measurement than you'll need to shim the neck at the top of the heel route.

I have 4 springs, the trem is parralel to the body. This is not the problem unfortunately
I know what you mean about the English, I'm French
Oh and about the neck: my neck leaves the body downwards if you see what I mean, it's something to do with the Floyd...
So the pocket is like this ...neck i_| body

Measure from the edge of each side of the fetboard to the edge of the strings.If they aren't an equal distance than the neck has shifted.
Also,make sure that the trem is seating properly on the pivot bolts.

You mean if by looking at the fretboard from the top, the e strings are of different distances to the edges? If so, my high e is further away.
And the trem sits well.

Sorry-I should have told you that you need to make this measurement at the end of the fretboard.

I was talking to johnjohn hehe, sorry not making it clear. The trem is parralel to the body.
