First of all, awesome song

I'm trying to work out what on earth he is doing during the part where the tempo increases and he plays a little lick (i think its on the guitar) my guess he is octaving his guitar, but its also very distorted, how on earth does he get it this distorted? and is he using a killswitch.

If not would this work? because i'm thinking of leaving my band to go solo and create sort of experimental rock music such as this.

Its an Electro Harmonix POG (polyphonic ocatve generator) that creates those sounds, this pedal is a big part of Jack's sound. A Whammy is pretty essential for his tone as well.
The obligatory gear list: Gibson SG standard,Maverick F-1,Epiphone Sheraton,'68 reissuse Jap Strat, Orange Rocker 30 and various pedals.

ok, but thats expensive, does the octave multiplexer do the same kind of thing?
