How can you be sure?  by Radiohead

The bass actually echoes most of the melody in the song, so it can sound a
little wack on an acoustic guitar. Try walking the E up to the A on the
"good things and bad" parts to fill things out a little bit.

Notes on the chords:

I'm not sure what to call the B that I hear in the song, but I think it
might be a B5. It's fingered thusly; essentially just a power chord.
e--X---
B--0---
G--4---
D--4---
A--2---
E--X---

Also, the A2-:A is accomplished through a hammer-on, like so:
e--0---2-2
B--0---0h2
G--2---2-2
D--2---2-2
A--0---0-0
E--0---0-0

I think the G#m employed in the chorus is played with some open strings:
e--0
B--0
G--4
D--6
A--6
E--x

And finally, the E5 in the chorus is played like an open D, but barred up 2
frets (kinda like how you might play an Eb)
e--x
B--5
G--4
D--2
A--2
E--0
