So, I was watching Volkerball (Rammstein) and one of their guitarists (Richard Kruspe) did a sound with his guitar I've noticed a lot of guitarists can do (Zakk Wylde, to name one).. He made almost a.. Shotgun effect? Like. I'm not real sure how to explain it. Not like Bullet's Scream, Aim, Fire reload sound, though. I could find the link for someone who doesn't know what I'm talking about, if they wanted. Any help on how to do it would be great.
