Why these settings

The GA15's small 6.5-inch speaker and solid-state drive circuit run thin and buzzy compared to a cranked 100W Laney stack, so push the amp's middle control to 8 and cap treble at 5 to avoid harshness. To compensate for the Stratocaster's brighter, lower-output single-coil bridge pickup versus Iommi's fat P90, roll the guitar tone knob back to 7 to shave off glassy bite and thicken the low-mids. A dedicated treble booster or overdrive pedal will eventually bridge the saturation gap, but this gets the heaviest playable punch out of the standalone amp today.

PRO TIPIommi tuned down a half step to Eb even on early takes, played with extremely light custom-gauge strings (.008 or .009), and hit power chords with heavy, downward, deliberate pick attacks using plastic thimbles over his fingertips—dig into the strings near the bridge with a stiff pick to emulate that percussive bite.
