01Holy War (High-gain distortion)

This is your primary gain source. The Holy War is voiced for modern metal, so pull the gain back from max to avoid fizz and keep the mids pushed for Iommi's wall-of-sound approach.

Why these settings

The Frontman 15 is a small solid-state practice amp with a bright, scooped Fender voicing and minimal headroom—it cannot produce Laney-style tube saturation on its own. The Holy War pedal becomes your entire gain stage; the amp is set clean (gain 3) to act as a flat platform. Mids are pushed to 7 on the amp to compensate for the Fender scoop and match Iommi's mid-forward bark. Your PRS humbuckers are hotter than Iommi's P-90s, so the pedal gain is set moderate (6) to avoid mud.

PRO TIPRoll your guitar's tone knob to 7 to tame the high-frequency sizzle from the humbuckers and get closer to the woolly, dark P-90 character Iommi had. Pick closer to the neck for the main riff to thicken the attack.
