look, i don't know if john mayer plays his own guitar for his music, because if he does, he is very good. i opened up some of his chords and i cannot even get through the whole song once. it is so complex! goodness! 83 is the song that i like most, he talks about how he wishes it were 1983 and how great life was for him back then. the guitar is really funky in it, and i wish that one day i could play like that. although maybe, there are more than 2 guitars playing, maybe..
