it might be a ROland pickup through a guitar synth but i doubt it, try plugging a DS-1 into the clean channel on your amp and turning the distortion up, idk but it kind of sounds like that.
The Mitch Clem formula
1)make jokes about rancid and NOFX (as if they dont already make fun of themselves)
2)make obvious punk puns, possibly related to food
3)make fun of Rancid and NOFX again
4)??????
5)PROFIT (and an army of internet fanboys)

I have a GNX3 FX pedal / workstation. sounds like they have a multi pedal as well.

Keep an eye out at GC and you can get one for $117 on clearance = like i did.
