the 13 monsters sound - to me - sounds so heavily based on multiple octaves that i would recommend trying a micro-pog (or proper pog).
and fuzz, obviously
FWIW, i can get a pretty close Lightning Bolt impersonation using a Micro pog with all 3 tones engaged, and a barker assmaster with the sensitivity turned up pretty high. this isn't what they use but will put you in the same region...
basically fuzz + octave. whammy for the really high bits.
EDIT from memory of some pix, he uses TWO boss ODB-3s. madman.
EDIT again - might be bi-amped, they use so many speakers...
