Why these settings

The CRUNCH amp type pushed by the Katana's internal Treble Booster delivers the aggressive front-end push that Tony Iommi achieved slamming a Laney Supergroup. Because your SG Standard '61 features humbuckers rather than Iommi's single-coil P90s, keep amp gain moderate at 6 to prevent excess low-end mud while pushing the midrange to 8 for that signature boxy honk. A slight presence lift adds the biting pick attack that cuts through the thick wall of distortion.

PRO TIPTony Iommi played with light custom string gauges (.008 or .009 set tuned down to D-standard or E-standard depending on the track) and light plastic thimble prosthetics on his fretting fingers, giving his attack a uniquely loose, sludgy vibrato—dig in lightly with a heavy pick near the bridge to mimic that distinct percussive bite.
