                        Give Chase - Tegan and Sara
-----------------------------------------------------------------------
Here's the version I used as reference. 
http://www.youtube.com/watch?v=CHknZ16Uu4U 
I'm still figuring out Sara's part.
Guitar 1 is Tegan, just distorted. Guitar 2 is (most likely) Ted 
and has a delay effect, which will change how the part sounds when played. 
You can adjust accordingly.

Tuning: standard
Verse, Guitar 1 palm muted: ("those windows...")
