I was pretty happy with the sweeps and most of the bends from the Sylosis video, but I don't know if I'll ever nail that scale run at 0:08. It's only a stock 3-note-per-string shape, but it's just an absolute bitch to play.
Not strictly a cover in the traditional sense, but i haven't got around to recording any guitar covers yet primarily due to not having a functioning web cam. But anyway...
8-string slap guitar idea I came up with last night, pretty Sikth-ish I guess. Sound is quiet as it was late and I need to tighten it up, but I thought it was cool enough, might turn into something.
