Why these settings

The Cort CM10G practice amp features a 3-band EQ and a dedicated overdrive channel without presence or onboard reverb. To match Randy Rhoads's cranked Marshall tone without his MXR Distortion + and EQ pedals, engage the drive channel with gain pushed to 8 and mids dialed to 7 to replicate his signature 500Hz mid-boost. Adding an MXR Distortion + pedal down the line will allow you to switch the amp to clean and capture the authentic clipping character.

PRO TIPPick forcefully directly over the bridge pickup with a heavy, sharp pick to bring out the bright, cutting harmonics of the iconic F#m intro riff.
