Californication

John Frusciante is documented as using a 1957 Gretsch White Falcon throughout the title track, with song-specific research pointing most strongly to a Fender Showman-style recording amp rather than his usual live Marshall pair. The exact amplifier and control positions are not conclusively logged, so the settings below are approximated from that documented guitar and likely amp while keeping the sound deliberately clean and dry.
