I've notaced a lot of people asking for this tab, and since I can't find another on the 
I worked it out myself.

Standard tuning
~ slide to
h hammer on/ off

This is the main riff, it plays once at the start and then at random points in the song. 
you can see Slack plays it differently than InSoc.

   F#m  A  G#   B     G#m  B  A#   G

                    ------------------| (Slack)
                    ---4---7---6---3--|
                    ---4---7---6---3--|
                    ---2---5---4---1--|
                      F#m  A  G#   F

After that just relentlessly hammer out that F#m. Every 2 bars change to D, (yes, it 
odd in standard tuning, but hey.) and then back every other 4 bars.

Here is whr thee solo starts, I have just tabbed the  basic one from the Information 
version, but from this it's pretty easy to work out Slack's * are the 
played during the solo.

Sorry if it's a tad confusing,  but I hope it helps.
