On his Earlier Cd's, he uses a Randall R100 (I think) which is a high gain amp. What he uses now is his signature Krank Krankenstien amp, which is a gain whore. You don't have to use effects, but it does color it up nicely.

Here's him plugging striaght into his Krank when Krank was still sprucing it up:

But yes, in that video, he uses a delay pedal, as did he use one for Cemetary Gates. If you listen to F***ing Hostile, he doesn't use delay, he has his wah engauged and possibly his chorus pedal as well.
