[Wei-Ming]

Hello all! I'm not sure whether this is the right forum to post this up.. So if it happens to be wrong, please forgive me.

I've recently got a Tele. and the intonation is very off.. I've read up online about it and tried to fix it myself.
The 4th, 5th and 6th strings are the problem. But the most off is my A string.. When the 12th fret harmonic is in tune, my fretted 12th note is towards sharp..

I have tried placing my bridge saddle closer to the neck and also further.. But the problem doesn't seem to go away...

There's some pics below of my bridge.. Hope someone could help me out here. Thanks a bunch!
