Keeping in mind in the past Korn's guitarists have used:
Guitars:
Ibanez UV
Ibanez RG-7 (basswood, long before PAF-7 was made)
Ibanez K-7
Ibanez S-7
Fender Strat (clean stuff on records mostly)
and now Munky's using a Gibson SG with P-90s for one or two songs live.
Effects:
too many to list, but used to use a custom-built Fuzz/Distortion pedal for a lot of stuff, and whammy, delay, chorus, flange, etc. very important.
Amps:
Mesa/Boogie Road King (only on new album/tour)
Mesa/Boogie Triple Recto.
Mesa/Boogie Dual Recto.
Hughs & Kettner (something or other)
Marshall (something or other)
Line6 Flextone II HD (Munky had one in his rig around "Follow The Leader")
and some random others in the studio I'm sure.
Still think the Road King and PAF-7 are the be-all-end-all of their tone?
