Why these settings

The Marshall Code is a modeling amp, so we select the Plexi/1959HW preamp model and engage the onboard distortion stomp block to recreate the MXR Distortion + frontend push. The Jackson JS22 ceramic humbuckers have plenty of output, so gain is kept at 7 while the mid EQ is pushed to 8 to replicate Randy's signature 500Hz mid-boost without needing an external graphic EQ pedal. Presence is null because the Code 50 faceplate features Gain, Bass, Middle, Treble, and Master Volume (Resonance and Presence are sub-menu power amp settings).

PRO TIPPick aggressively near the bridge with a stiff pick to get the sharp, percussive attack of Randy's muted F# minor riff, and use light palm muting on the pedal tone while letting the moving notes ring out sharply.
