So Im starting to try and learn songs by ear and came across J.D. DeServio playing In This River just on bass. I've learned pretty much the obvious parts but somewhere along the line the sound fuzzes up and I really need help just figuring this out. Any and all help is appreciated.

Heres the video

that video has shit quality... Can you narrow down where you are struggling?

He doesn't change anything. He's got a delay and maybe a little chorus? When he plays faster you can hear the fuzz, but I think it's from the cell phone or whatever that is filming him.
I have:
Acoustic B200H+B115 cab, Schecter Stiletto Custom 4, Rondo Fretless, Boss EQ-7.

Some men just want to watch the world burn. And they work at Behringer.
