Billie Joe's Blue
The most iconic of Billie's guitars dates back to the band's early-90s, 924-Gilman-Street days: a super-strat coined Blue. The stickered axe is a Fernandes Stratocaster copy that he got for his birthday when he was 11. Armstrong uses Blue on primarily Green Day's earlier songs like "Basket Case," "Longview," "Brain Stew," and "Hitching' a Ride," so the guitar is tuned to Eb and is strung with Ernie Ball Slinky .010 - .046 strings (the rest of Armstrong's guitars are tuned to E standard).
