One fateful day in the early 1960s, Paul McCartney walked into a music store. A lefty, he thought Hofner's symmetrical violin-shaped bass would look "less daft" on stage with right-handed guitars. Little did he suspect that this bass would become one of the most iconic instruments in rock history. This Hofner Vintage '63 500/1 Beatle Bass is modeled after McCartney's 1963 version.
