Sometimes it's worth playing something really “out of your league”, right? :) Dunno, I like the song even though I'm not really an RHCP fan. Also, I don't slap, and “Under The Bridge” is a nice example of Flea playing a non-slap melodic part. A bit challenging but totally doable even if it's not really your style.
I know there are a few versions of bass tabs for this song. I just chose the one I liked the most. So, excuse me if it's not exactly what Flea played, note to note.
Enjoy! And I'd like to remind you to donate to the “Come Back Alive” fund to help Ukrainian army in their fight with Russian nazis: https://www.comebackalive.in.ua
