Why these settings

Selected the '70s Rock model on the Mustang LT25 to simulate Frusciante's pushed vintage Marshall clean tone. Mids and treble are pushed to 7 to deliver the percussive attack and upper-mid bite of the CE-1 preamp, while gain is dialed back to 4 to prevent the single-coils from breaking into full distortion. The Mustang LT25 lacks a dedicated presence knob, so presence is nulled.

PRO TIPMute all unplayed strings aggressively with your fretting hand thumb and index finger while striking all six strings with wide, rhythmic pick strokes to get the iconic percussive snap.
