Why these settings

The NUX MG-300's Plexi model provides John Frusciante's characteristic Marshall bite, dialed to edge-of-breakup so hard pick attack crunches while muted rakes remain articulate. The onboard booster emulates the Boss CE-1's famously gritty preamp section pushing the front end. Keep the treble and presence elevated to let the Stratocaster's percussive top-end snap cut cleanly through the mix.

PRO TIPFrusciante plays the signature riff by aggressively striking all six strings on every downstroke while muting the unused strings entirely with the left hand thumb and spare fingers; the percussive string-rake noise is essential to the tone.
