The Pixies
“Gouge Away”
From “Doolittle”

I’ve never felt 100% about this one, but this is the way we play it.

It’s as easy as doing this the whole song

A|-----------------77777777--------77777777-
E|-4444444477777777--------44444444---------

Every now and then, you’ll get the “chorus” where you might want to do this.  A very slight, but noticeable difference.  (In case you don't see it, it's a slight pause before the second E4)
