Here's "El Scorcho" on the guitar. I'm a bassist, but I'm positive that this is
what Rivers (the guitarist) plays because I've played it so it sounds just like
it when my friend brought his guitar over. It's tuned regular when you play it.

And that's it. Later in the song, he adds some effect to the guitar which makes
it sound weird. By the way, if you forgot what the little "b" in the tab is, it
means to bend the string up. And the 6.5 and 11.5's in the tab are just what I put
because I don't know what to write after putting the "bend" sign. Usually, you'd
put like a "7" or something, but the sound doesn't go higher than the sixth fret.
But anyhow, that's it. It's not hard, so you can probably learn it in no time.
