Chords (in standard tuning, BTW):
e| 2 - - - 5 4 0 |
The opening "riff" is just the F# chord (2nd fret position) with loads of
reverb, another way to get that "wavy" feeling from just playing the one
chord is to position your hand to play the F# as I've shown you above,
except hammer on the first-finger barre on the 2nd fret to begin the riff
(^ = downstroke, v = upstroke):
F# ^ v ^ ^ ^ ^ ^ do this twice; the second time the lead guitarist
e|-----2-2-2-2-2-2-2-| (on tour, Johnny) plays:
B|-----2-2-2-2-2-2-2-| (4/5\4) just before the rhythm guitarist
G|-3---3-3-3-3-3-4-3-| (on tour, Craig Gannon) plays the next chords
