I tried to play this one correctly, especially the intro that's driving everybody crazy. But I wasn't able to find a good tab for the intro and I ended up playing it by ear.
Lately I found a good Gpro tab done by Giezoe ( http://www.ultimate-guitar.com/tabs/r/red_hot_chili_peppers/californication_live_guitar_pro.htm ) but the intro track wasn't that good, so I modified it a little and tabbed it the way I play it. It sounds almost perfect. Hope you like it
