Why these settings

The Spider IV 75's Metal Red model emulates the Mesa Dual Rectifier used on the record, so keep gain at 6 because Spider preamps saturate early. Scooping mids slightly to 4 and pushing bass to 7 recreates the aggressive modern nu-metal thump without turning the IBZ-6 humbuckers muddy. The Spider IV 75 has no physical presence knob, so highs are dialed via treble at 6 for cut without harsh sizzle. Clean intro/verse: switch channel to Clean Red with volume rolled back to 7.

PRO TIPBrad Delson recorded this riff in Drop C# tuning; drop your low D# string and hit downstrokes aggressively near the bridge to tighten up the palm mutes and match the punch of the recorded double-tracked wall.
