Why these settings

Your Strat's single coils are brighter and lower output than Iommi's P90s, so I pushed mids to 8 (vs a typical 6-7) to compensate for the Strat's natural scoop, and rolled treble back to 5 to avoid ice-pick highs. The Brown amp type on the Katana nails the British valve stack character. Rolling your tone knob to 7 warms the bridge single coil closer to P90 territory.

PRO TIPTune down to C# standard (C#-F#-B-E-G#-C#) — this is non-negotiable for the song's crushing weight. Use heavier strings (.011-.052 minimum) to maintain tension and prevent flub at that tuning. Palm mute hard right at the bridge saddles for that iconic chunk.
