Why these settings

The Dean Vendetta's humbuckers provide solid output, but Randy's signature tone relies heavily on the pronounced mid-range push of an MXR 10-Band EQ driving a crunchy British stack. Within the Zoom G1X Four, running the D-PLUS/GoldDrive model directly into the MS 800 amp block with boosted 800Hz and 3.2kHz delivers Randy's signature vocal bite without becoming harsh. Keep the amp gain moderate around 6 so the distortion pedal adds the harmonic saturation rather than overloading into digital fizz.

PRO TIPPick aggressively near the bridge with the edge of a heavy pick for sharp articulation, and use tight, fast wrist vibrato on sustained notes to emulate Randy's classical-influenced technique.
