The Gibson Les Paul Junior 1956 Sunburst Electric Guitar is used by guitarist Billie Joe Armstrong of the world-renowned rock band Green Day. Billie Joe named this guitar "Floyd," which served as the inspiration for his signature Gibson model and remains his favorite guitar. In an interview for Guitar Player he also notes that this guitar was used for recording "21st Century Breakdown". "I mainly played a ’56 Gibson Les Paul Junior, but I also had a Slash model Les Paul, a Jimmy Page model Les Paul, and my ’59 ’burst."
