@ Mahip: That thread is not of too much use
The best thing to do is to go to Google and type in the name of the song you want.
Indian Guitar Tabs is pretty decent, as far as I know.
Even the big daddy of all guitar tab sites,
ULTIMATE GUITAR TABS ARCHIVE | 200,000+ Guitar Tabs, Bass Tabs, Chords and Guitar Pro Tabs! has some Hindi tabs.
If you have GuitarPro installed on your PC, then try
MySongBook - The Ultimate Guitar Pro Tablature Archive. I got the Adat tabs from there long back. Of couse, they are not as detailed as say, some Metallica or Maiden tabs!
Cheers!
