Why these settings

On the NUX MG-300, use the SVT/MLD bass preamp model with the bright switch engaged and mids scooped at around 400–500Hz to match the aggressive 'Justice' isolated tone. Since your Jackson JS32 has passive high-output humbuckers rather than an active Alembic bass preamp, use the onboard compressor and an overdrive block set as a high-treble boost to simulate the ultra-fast metallic clank. Reverb is set to 0 to keep the rapid 16th-note galloping articulate and tight.

PRO TIPDig in hard directly over the bridge pickup with a heavy downward attack (or a stiff 1.14mm+ pick) so the strings hit the frets, producing that distinctive metallic percussive snap essential to the 'Justice' tone.
