Great solo from Jeff Tweedy, here's the blueprint, keep
 in mind that in order to sound
the recording you will need lots of feedback and some 
sort of phaser/flange pedal and the
here are full vibrato and require you to listen to the 
recording to hit all the notes
perfect.  With all that said heres the tab:

Capo on 3rd fret (all open notes are found on 3rd fret,
 all other notes are as they are written)

|----------------------13~~~-------15h17~~17b18b17~~---
