Why these settings

The Behringer HD300 provides the heavy 80s thrash distortion, so the MG30CFX is set to its clean channel with gain dropped to 2 to prevent muddy double-gain stacking. To compensate for the Telecaster single-coil's piercing top end compared to Dave Mustaine's high-output humbuckers, tone on the guitar is rolled back to 8 and amp treble is kept moderate at 5. The MG30CFX lacks a physical presence control, so that parameter is omitted.

PRO TIPAnchor your palm firmly against the bridge saddles for tight, percussive chugging, and use aggressive downward pick angling near the bridge pickup to emulate Mustaine's raw pick attack.
