I'm pretty sure this all (?) right :)
Tuning (I don't know if this particular tuning has an actual name)
This is what I use:
FC
G#D#
A#D#
this is drop D, tuned UP half a step.

pm *= palm mute
x= mute string

Guitar 1 is the main guitar that you can hear
Guitar 2 is the other guitar in the back ground most of the time :)
