Why these settings

The Mustang LT25's Vintage 50s model provides the glassy, chimey Fender clean platform, dialled to gain 4 for immediate touch-sensitive breakup. Because your Ibanez GRG320FA has hotter humbuckers than Frusciante's vintage single coils, bass is pulled down to 4 and treble pushed to 7 to retain cutting funk clarity without mud. The LT25 does not feature a physical presence knob on its top panel.

PRO TIPFrusciante's percussive attack relies on aggressive full-hand muting: use your fretting hand's thumb and index finger to mute all unplayed strings while aggressively strumming across all six strings for every single note.
