Best done with a Wah pedal

Work out the Rhythm yourself, because it would take me ages to type every chord  
After this, its back to the Pre-Chorus Riff
Then:

e|----------------------------------------------------------------------
B|----------------------------------------------------------------------
G|--------------------7-----10-----9-----8------------------------------
D|-0--------------------------------------------------------------------
A|-0------------------5-----8------7-----6------------------------------
D|-0--------------------------------------------------------------------
After playing the D chord, the switch is toggled.   
Then The Main riff joins in.

In the next chorus a Wah pedal is used to play the rhythm part.
