hey guys,

ive been trying to learn this song. it's quite easy except for the fact that it freakinly hurts my left thumb.

do you guys have any idea to reduce this or just any thoughts about it.

Apparently when Dave first started playing the song, he would play it without the B string fretted at the 5th fret. This will free your pinky up to play the 4th fret on the G string, and make the stretch on your hand a little less worse. That should help out with the pain in your thumb until you get your endurance up a bit more.
