Tab is almost perfect, well i'd say you just copied out the official tab book cos i have it and its exactly the same, tho there is no drop 'd' tuning. Its standard Tuning EADGBE
It`s copied from the book and it`s impossible to play like this man, it also don`t always sounds good. Some chords are just impossible like I said and Matt does it different.
It's an awkward chord to play, but it is possible if you rest your little finger across the D and G strings on the 12 fret (though still pretty hard to switch to mid song).
I tend to play it like so: -10- -9- -x- -12- -10- -0-
For that terribly hard chord: You could try using your thumb on that bottom note, the 10 on the A string (G), kinda like the RHCP guitarist. I think that technique is called a thumb trigger or something. That chord is just a bitch, though. No other way to describe it. (Besides E7#9 that is...)
