The basic progression throughout this song is:
B, D, E, D, A, B, D. All in powerchords, you'll have to listen to it to get the timing.
The bridge section is basically;
[ Tab from: http://www.guitaretab.com/b/built-to-spill/64894.html ]
e|--------------------------------------------------------------------|
B|--------------------------------------------------------------------|
G|--------------------------------------------------------------------|
D|--------------------------------------------------------------------|
A|-----------------------------2-0------------------------------------|
E|-2-0-2-0-2-4-5-4-2-0-2-2-2-2----------------------------------------|
The melody guitar lines are in B minor pentatonic at the 5th and 7th position, best to improvise them.
This is my first tab and it's from memory so sorry if it's not perfect!!
Cheers!!
