I don't really remember what I did for the bias fx tone, but I started from the already existing preset "DMO Among The Living" and changed a few things, but the preset alone is already pretty good I think... As for the tabs yeah, I always get the notes myself, online tabs always have notes wrongs or somthing, for the whole song, I listened to the isolated guitar track on RU-vid, BUT there is a video online, where scott ians shows how to correctly play the war dance riff, here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VlpdMRXOBNY.htmlsi=fAndEQERmOk9mYTn Hope it will help !
