Why these settings

The Mustang LT25's Metal 2000 model reproduces the hot-rodded Marshall crunch, while an onboard overdrive block set with low drive and high level mimics Kerry King's boost tightening the front end. Mids are kept prominent at 7 because 80s thrash cut comes from upper midrange bark rather than a modern scoop. The LT25 faceplate has no physical presence knob, so top-end attack is shaped strictly via the treble control at 7.

PRO TIPUse heavy, rigid 1.0mm+ picks and pick right against the bridge saddles with aggressive, angled downstrokes to get the razor-sharp percussive attack required for Slayer riffs.
