Before I start, I have a Fender Aerodyne jazz. The A string buzzes on the 2nd or 3rd fret when I pluck the open string. I've checked the frets, they seem to be level. No other strings buzz, just the open A. I've heard this is somewhat common, just looking for some advice.
 
Look at the nut (from the head) and see if it sits lower than the rest of the strings. It could be that your A string has eaten it's way deeper into the nut. If you use round wound strings this can happen after awhile. The only cure that I know of, is a new nut, for this.

Wouldn't that cause it to rattle on the first fret instead of the 2nd or 3rd?
 
My Dean 5 string acoustic would get some rattle (B string 5th fret, and E string 5th, 6th, and seventh) when I was using bronze strings along with temp. and humidity changes it would need a slight truss rod tweek would be necessary to keep it at bay every, about every 6 months or so. The root problem I found was that the PO had round wound strings on it and they ate their way into the nut. Now, with tape wound strings and increased diameter most of my problems are solved (increased dia. keeps the strings higher in the nut, above the sharp point of the grove in the nut) but, if I go back to the original bronze strings I think I would have to replace the nut. Larger diameter bronze wound strings like round wound strings are a lot like taking a round file in the grove if the nut is soft material.
 
It may be that the groove in the nut for the "A" string in cut too low. If you have a feeler gauge, you should check the
nut action. If the gap between the A string and the first fret is lower than the gap on the other three strings, you may
have found the problem. Solution? You should have a new nut installed with a shallower depth for the A string.
 
Got my white 2011 Epi Custom Shop Thunderbird back from the shop about a month ago, had the nut replaced and they did a setup on it as well. Problem with the setup was that when I got it home and looked at it the bridge was set way high in the rear and way low in the front, which is exactly opposite of what I've read and been told (mostly here) about proper setup for a floating 3-point bridge. Action was also a bit higher than I like it. So I've redone the setup so the bridge is a bit higher in front than back and got the action where I like it (low). The reason it came back that way according to the guy who did the work (very reputable shop, he's done two of my other basses and did a fantastic job on them) was to get rid of a buzz at the 2nd fret on the A string, which was a known issue when I took the bass in to be worked on thinking it was caused by the jacked up nut that I had him replace. When I fret the A string at the 1st fret (A#) I get a very distinct buzz. Goes away when I play the B (press the string down at the 2nd fret) and on up, this is the only place on the entire freaking fingerboard is buzzes and it's making me crazy. I only need that note on a few songs but it's just a real PITA to have to work around.

To me it seems like I could just file the 2nd fret down a bit to get rid of the buzz, the luthier tells me that it's not that simple, that it needs a full fret job to get everything even. Really don't want to put another $100 in it for a full fret job that IMO it doesn't need. If anyone has any input on how to solve this I'm all ears (or eyes as it were). FWIW I did try putting some aluminum foil under the A string at the nut to raise the string a bit at the nut but didn't help so took it back out (I'm obviously no expert).
 
Here are some pics, needs a good wipe down. If you need some more let me know.

What's the A string / 1st fret gap when fretted at the 3rd? Re-set your witness points as a matter of routine. Your string spacing at the bridge looks peculiar...are you trying to align with the polepieces or fingerboard? How much relief do you have on board?

Yeah I was just aligning the polepieces, but that I just did the other day to see if it would make any difference in sound. It's been buzzing way before that. I'll get you a picture of the spacing when I can.

EDIT: The A string is just barely resting on the 1st fret when I fret the 3rd.

Don't sweat the spacing...just an observation. The string should not be resting on the 1st fret; you should see a gap ~.003-.005". How's the relief? Any chance you kicked it into an "S" curve?
