Use the amp's built-in overdrive effect to simulate the treble booster push Iommi used. This adds the cutting attack without fizzy highs.

Why these settings

Your Epiphone SG with humbuckers is hotter than Iommi's P90-loaded '65 SG, so treble drops from 6 to 4 and gain stays moderate to avoid mud. The Mustang's British 80s model has more compression than a real Laney Supergroup, so mid is pulled back slightly to prevent honk. Rolling the tone knob to 5 replicates the dark, woolly character Iommi got from his guitar's tone control.

PRO TIPTune your guitar down to C# standard (C#-F#-B-E-G#-C#) — this is non-negotiable for the actual pitch and string floppiness that defines the Master of Reality sound. Use heavier strings (.012-.056 or higher) to maintain tension and prevent the low notes from turning to mush.
