The Upsetter Jack Johnson Jack Johnson - The Upsetter I haven't seen any tabs of this song, so here's a few various parts and some chords to get people started. I'm sure someone will create a better tab soon, but at least this is something to work with in the meantime. I think the song is in the key of C. During the solo I think there are 2 guitars, likely dubbed in the studio. The song is mostly piano with Jack playing electric guitar riffs. Feel free to comment or work this into a more comp (guitaretab.com)
