John Frusciante’s Fender Silverface Dual Showman (Head)

This amp seemed to have been used for the entirety of the Californication tour, paired with a Marshall Silver Jubilee and a Major Major 200W. It was abandoned by the time the band went on the By The Way tour in mid-2002, and since then John resorted to using Marshall amps exclusively on stage.

Based on the photos and statements from John, he also used a Fender Showman amp in the studio for Scar Tissue and Otherside. But, based on the photos, this was not the same amp that John used live, because that amp has a black plate and brown grill cloth, while the tour amp has a silver grill cloth, and likely, a silver plate (better photos are needed in order to confirm this).
