Why these settings

The Fender Rumble 40 is a clean bass amp with a 4-band EQ and lacks guitar-focused preamp distortion, so its onboard Overdrive switch and Gain must be pushed to 8 to provide maximum crunch today. Set Low-Mid to 7 and High-Mid to 6 on the Rumble panel while trimming Bass to 5 to avoid low-end mud. Single coils on the Affinity Strat lack the output of Mick Mars' Seymour Duncan JB humbucker, so rolling the bridge tone knob down to 8 helps tame harsh highs until a dedicated high-gain distortion pedal is added.

PRO TIPMick Mars used aggressive, heavy palm-muting right against the bridge saddles on the chugging 16th notes; pick firmly near the bridge to maximize harmonic bite.
