Why these settings

The Mustang LT25's British 80s model emulates the Marshall JCM/Plexi crunch that drives Billie Joe's sound. The LT25 physical panel only features Bass and Treble controls (no Mid or Presence knobs), so set Treble to 7 for top-end bite and Bass to 5 to avoid boominess. Your Ibanez humbuckers provide more output and low-end warmth than Billie Joe's single P-90, so keeping the bass flat and treble prominent retains clarity.

PRO TIPHit power chords aggressively with hard, sharp downstrokes near the bridge to replicate Billie Joe's percussive transient punch.
