I can't find the tab/chords for this anywhere. It's just a basic blues riff, but I have absolutely no idea how to do it, and I don't listen to blues so I wouldn't even know what else to look for :P. Could someone maybe find me a tab for this?

I'm tone deaf, so I can't help you too much, but if you've got a better ear than I do, start on the low E string open and the A string at the second fret. Pluck those two, and if it sounds right, there's your first chord and the key of the song. If it doesn't work, move the shape up the neck, so E would be at first fret, A at third, and so forth. Also, when the chord gets higher, it's just adding a whole step up on the A string.

I wish I could be more help, but again, I'm tone deaf. If you figure it out, let me know too, cause I'm listening to it for the first time in a while and remembering how good it is.
