Tuning: CFA#D#GC (that's two whole steps - anything lighter than 10's will be way too floppy)
Note: 10, 11, 12 etc is fret 10, 11, 12 etc, not fret 1 followed by fret 0.
Riff 1 - is a descending line with the open F as a pedal note (at least, i think that's what it's called)

|--0-0--0--0--0-0----0-0---------0--0--0---------|

that's the basic pattern. Josh doesn't stick rigidly to this, so feel free to embellish
Riff 2 ("There's no one here...")
|-------------------------------------------------------------------|
|-------------------------------------------------------------------|
|-------------------------------------------------------------------|
|-7-5-7-9-7-5-4-5-7-5-7-9-7-5-4-5-7-5-7-9-7-5-4-5-7-5-4-2-4-2-4-5-7-|
|-------------------------------------------------------------------|
|-------------------------------------------------------------------|
Riff 3 ("ah...")
|----------------------------------------------------------|
|----------------------------------------------------------|
|------------------------------------------------9999-9999-|
|--10101010-10101010-9999-9999-12121212-12121212-----------|
|-0--------0--------0----0----0--------0--------0----0-----|
|----------------------------------------------------------|
after repeating this a few times he plays a new riff:
|--------------------------8h12-|
|-----------------------10------|
|----------------------9--------|
|----------10--10-10h12---------|
|-12p10h12---12-----------------|
|-------------------------------|
and then things descend into improvised bends and whatnot, around the 12th fret
