Why these settings

The Mustang LT25's 'Metal 2000' model replicates modern cascaded high-gain, allowing you to achieve the tight Mark IIC+ saturation directly from the amp. We scoop the mids down to 2 while pushing bass to 8 and treble to 7 to emulate the classic Mesa Boogie 5-band graphic EQ 'V' curve used on the album. The LT25 physical faceplate lacks a presence knob, so presence is nulled, and reverb is kept strictly at zero for that bone-dry rhythm precision.

PRO TIPAnchor your palm heavily across the bridge saddles and execute aggressive, rapid downpicking with a stiff, pointed pick (1.0mm+) right against the bridge pickup for the razor-sharp mechanical percussive attack.
