Why these settings

The Zoom MS 800 amp block paired with the DIST+ model recreates Randy's signature front-end clipping and Marshall punch. The GIO humbuckers provide plenty of output, so keeping the EQ block pushed at 400Hz-800Hz delivers the iconic mid-forward bite while keeping the low end tight. A very subtle plate or room reverb can be engaged in slot 4 if playing through headphones.

PRO TIPRandy's razor-sharp attack comes from hard, angled downstrokes near the bridge saddles; keep the pick grip tight and use firm wrist-driven alternate picking on the F#m riff.
