John Frusciante’s Moog MF-105 Moogerfooger MuRFaccess_time First seen circa 2005
According to an interview John gave to Guitar Player magazine in 2006 (source available below), he used the Moog MuRF on the solo for ‘Tell Me Baby’.
The effect was also featured on the second verse of ‘Dani California’ (listen to the video below).
The second verse begins with a couple of guitars playing in harmony. After they were recorded, I ran them through a Moog MF-105 MuRF (Multiple Resonance Filter Array) pedals six times and recorded the results on individual tracks.Red Hot Chili Peppers’ John Frusciante, Guitar Player magazine, 2006
