Why these settings

The Fender Mustang LT25's Metal 2000 model captures the aggressive, mid-heavy crunch of a boosted JCM800 without needing an external drive pedal. We keep the mids pushed at 7 and bass tight at 5 to reproduce Kerry King and Jeff Hanneman's punchy thrash bite without flubbing the 8-inch speaker. Reverb is set to 0 for an authentic bone-dry studio attack.

PRO TIPUse heavy, consistent downpicking right next to the bridge saddles and keep palm muting exceptionally tight to achieve the percussive, mechanical chug characteristic of the track.
