Members of Pinhead Gunpowder have purchased a brand new sound system including a new mixing board for legendary venue, 924 Gilman. According to the SFBG blog:

Weeks before the show, the band – which not only includes Billie Joe Armstrong, but also Green Day's tour manager, Bill Schneider, and their touring second guitarist, Jason White – offered to donate money to the club. Instead, Gilman told the group that a new sound system would be the best way to help, and it would also make the sound better for their show. The band immediately obliged by installing beautiful new JVC speakers, and later provided a new mixing board as well. According to the club, the band instigated the donation on their own and was not encouraged to make one.

An unsanctioned video of the band's performance was posted on Youtube.
