I think I got this hammer on technique in the intro from Nuno Bettencourt. Pluck open string, hammer on string, then also hammer on string right below (while palm muting for a percussive attack).
The ending is my attempt to blend a hoe-down with modern prog metal poly rhythms.
Mostly Diezel VH4...some JCM 800....some acoustic guitar....goofy synth sounds courtesy of Reason...all kinds of wacky fun.
