Why these settings

The Marshall MG30CFX lacks an onboard graphic EQ and presence control, so the classic Mesa V-curve is simulated by dropping the mid knob to 3 while pushing bass and treble to 7 on the high-gain OD-2 channel. Because your Epiphone Les Paul Studio has passive humbuckers rather than James Hetfield's active EMG 81s, keeping gain at 7 provides tight saturation without turning flubby on palm mutes. Keep the amp reverb at absolute zero to maintain the dry, punchy tracking of the original record.

PRO TIPEvery single rhythm note during the main riffs must be played exclusively with aggressive downpicking and hard palm-muting right against the bridge saddles to achieve the record's tight percussive punch.
