Why these settings

The Mustang LT25's 'Metal 2000' model emulates modern cascaded high gain similar to Adam Jones's Diezel VH4 and Dual Rectifier blend. Because the Player Strat has lower-output single coils compared to the Duncan Distortion humbucker, keep gain at 7 and back the tone knob down to 8 to shave off excessive single-coil top-end harshness. The Mustang LT25 faceplate has Bass and Treble knobs only (no hardware Mid or Presence controls), so set internal cabinet/EQ presets to flat.

PRO TIPAdam Jones's signature heavy attack comes from aggressive, consistent downpicking right near the bridge saddles with a thick pick (around 1.0mm-1.14mm) combined with palm mutes released right on the beat.
