Why these settings

Your Mustang LT25's Princeton model nails this tone directly — it's the same Fender voicing Alex G uses. Gain at 3 gives that slightly saturated-but-clean feel when you dig in. Treble rolled to 4 and tone knob at 6 soften the Jet's bridge-heavy brightness to match the wooly, muted quality of the recording.

PRO TIPPick closer to the neck (over the fretboard) with the fleshy part of your thumb or fingers rather than a hard pick attack — this is how Alex G gets that pillowy, rounded note bloom on the record.
