Why these settings

The MG15R's OD channel is voiced brighter and thinner than the Mesa Triaxis, so mid is pushed to 7 to compensate for the Marshall's natural mid-scoop. Treble dropped to 6 to avoid fizz—the MG series gets harsh quickly above 7. Your Jackson's high-output humbuckers approximate the EMG 81's compressed punch, so gain stays moderate at 7 rather than maxing out.

PRO TIPTune down to E♭ (half step down) to match the recording—this adds thickness and sag that partially compensates for the MG15R's solid-state tightness, and your Jackson will handle the lower tension fine with its 25.5" scale.
