   Light Overdrive

A|-5-X-8/10-X-8/13-X-8/10-X-8\-|
E|-3-X-6/8--X-6/11-X-6/8--X-6\-| 

I'm not 100% sure about the Mute Notes but I can hear light Mute Notes in the YouTube
video so you can choose to add/take them away if you wish.

This is played when the Drummer quits with the fast snare drum-roll and starts using the 
Cymbals.
I like to play it like this, but you can just play Fig. 1 without the Mute Notes.

I can't work out the rest from a YouTube vid so you can just improvise with these chords:

   G5  G    Bb5  Bb    C5  C
E|-----3--|------1---|-----0--| 
B|-----0--|------3---|-----1--| 
G|-----0--|------3---|-----0--|
