Karl Sanders uses rather vintage equipment, kinda surprising considering the death metal style. Anyway, Nile tunes to Drop-A tuning, seems strange on 6-string guitars, but that's what they do, I've e-mailed Karl to find out their tuning. This riff is the middle part of Barra Edinazzu, it's the only riff I have because my pitch is not very good so I can't figure out stuff very well. However, when I saw them live, I watched Karl closely, and this is how he played the middle riff. |-------------------------| |-------------------------| |-------------------------| |-------------------------| |-0-5-0-6-0-5-0-6-0-5-6-7-| |-0-5-0-6-0-5-0-6-0-5-6-7-| then the riff changes to tremolo picking as follows. |-------------------------| |-------------------------| |-------------------------| |-------------------------| |-------------------------| |005500660055006600556677-| I know it's only two riffs, but I thought I should post 'em anyways.
