Why these settings

The Katana 50 MkII lacks a dedicated presence knob and has a modern voicing, so the Crunch amp type with the internal boost provides the vintage Laney power-tube breakup. Your Les Paul humbuckers have warmer lows and slightly less upper-mid cut than Iommi's P-90s, requiring bass dialed back to 5 and mids pushed to 8 to preserve clarity. Setting treble to 7 delivers the bite historically supplied by the modified Rangemaster treble booster.

PRO TIPIommi tuned down to standard D on later records, but Iron Man on Paranoid is in standard E with light strings; pick firmly right near the bridge to accentuate the signature metallic attack.
