My ear is telling me those are octaves and to me they look like he's playing them, so, if they're not my bad.

Anyways, Is it some sort of technique or some effect? I've been trying to imitate it but it doesn't sound right and I assume it could be some technique. Anyways, I've tried strumming fast but to no avail will it sound proper... Maybe I'm doing it wrong?

Sounds like fast octaves with a bit of fuzz and perhaps some delay. Haven't tried playing it though. He does bend one of the octaves.
