Why these settings

The Mustang LT25's Metal 2000 model approximates a hot-rodded Marshall. Mids pushed to 8 captures the JCM800's signature bark essential for Slayer's riff clarity. Bass dropped to 4 (vs original's 6) because the Fender-based modeling tends toward flabbier lows—keeping it tight preserves palm-mute definition. Treble at 5 avoids the fizz that digital high-gain can produce.

PRO TIPTune down to Eb standard—Slayer used this tuning on the entire South of Heaven album, and the riffs will sound thin and wrong in standard tuning. Your Ibanez's stock Infinity humbuckers have enough output to get close, but pick right over the bridge pickup for maximum attack on the palm-muted sections.
