Green Day’s third album Dookie turns a whopping 25 years old in 2019, and to celebrate, the band is teasing some pretty cool equiptment.

Frontman Billie Joe Armstrong shared a photo of a guitar pedal with Dookie‘s album artwork. He captioned the photo, “Anyone going to NAMM?” which fans believe is a reference to a music trade show in Anaheim, California where they think the pedal might become available.
