John Frusciante’s MXR Phase 90
First used in the early days during the Mother’s Milk/BSSM era. During the recording of the Californication album, however, John borrowed an MXR Phase 100, but as the band went on tour, he seemed to have purchased a Phase 90 for himself and used it live from then on.
It is unknown whether he used this phase shifter exclusively, but it seems to have been on John’s pedalboard most of the time during the Californication tour at least. He seemed to have switched to a Moog MF 103 Phaser during the By The Way tour. But, in 2022 during the Unlimited Love tour, he went back to using the MXR (see John Frusciante’s 2022 Pedalboard).
I have an Ibanez wah-wah pedal, because it has a wider range than the others. I use a Fuzzface and a Boss distortion pedal, and an MXR phase shifter, and that’s about it.
