Slipknot fans -- you're on notice. Mick Thomson, the masked metal band's guitar player, will be in Fresno on Thursday to sign autographs at Spitzer Sound Stage.

The event starts at 7 p.m. and is free to the public. It's one of two autograph signings Thomson (aka No. 7) is doing in California this week through Ibanez guitars. He's in Sacramento on Friday.

Sound Stage is expecting a crowd of "anywhere between 100 and 500 people." The music store has already fielded calls from people as far away as Arizona who say they're flying in for the autograph signing.

Slipknot fans are a dedicated bunch.
