Marshall’s new Billie Joe Armstrong amp is built for Green Day nostalgia

COMING JULY 21: Marshall’s $3,999.99 1959BJA Billie Joe Armstrong Artist Signature amp arrives with a handwired 100W build, Dookie-inspired tone tweaks, and a baby-blue finish paying tribute to Billie’s first guitar, Blue.

The baby-blue Marshall amp spotted behind Billie Joe Armstrong during Green Day’s 2026 Super Bowl performance finally has a name. Marshall has officially unveiled the 1959BJA Billie Joe Armstrong Artist Signature amp, a handwired 100W amplifier created with the Green Day frontman to recreate the distinctive tone behind the band’s breakthrough era.

The launch marks Marshall’s first artist signature amplifier in 14 years, and it’s been a long time coming. When Billie Joe Armstrong took the stage with Green Day at the 2026 Super Bowl, eagle-eyed fans spotted a striking baby-blue Marshall head sitting behind him, sparking plenty of speculation about what the band was using. Turns out that mystery amp was a preview of Marshall’s latest collaboration.

Available from July 21, the 1959BJA Billie Joe Armstrong Artist Signature amp will cost $3,999.99 in the US and will be sold through authorized Marshall retailers and on its official website.

The 1959BJA features a custom “Dookie Mod” inspired by the modified sound Billie Joe Armstrong developed with producer Rob Cavallo during Green Day’s breakthrough years. The amp is tuned to deliver the heavier distortion, fuller sound, and aggressive guitar tone associated with Billie Joe Armstrong’s classic Green Day sound.

The baby-blue finish takes inspiration from Billie Joe’s first guitar, Blue, while brass and silver panel details, custom branding, and Billie’s signature on the front and back panels give it a collector-worthy look. Unlike a traditional combo amp, the 1959BJA is a head-only unit, meaning guitarists can pair it with the cabinet of their choice.

The 1959BJA is built for guitarists who want more control over their sound, with settings for gain, volume, presence, and EQ. It also supports different speaker cabinet setups, making it flexible enough for both stage and studio use.

For Billie Joe Armstrong, the collaboration represents a full-circle moment with a brand that has been part of his musical journey for years. “I’m so overjoyed to have my own signature Marshall amp,” Armstrong said. “These amps have been a part of my musical life, from my heroes down to little old me.”
