Why these settings

The GE100's Cali Mark model captures the liquid preamp gain of the Mark IIC+, while cutting the amp mid knob to 2 and setting an aggressive V-scoop in the onboard graphic EQ block recreates the classic studio parametric notch at 800Hz. Your Harley Benton's bridge humbucker has sufficient output, so the front Tube Drive block is dialed with gain low and level high purely to trim flub and focus the attack. Clean interlude: switch to the GE100 clean preset or bypass DS/OD and roll guitar volume back with neck pickup selected.

PRO TIPEvery signature downstroke in this track relies on strict right-hand muting right against the bridge saddles; angle your pick slightly forward to get the percussive click before the note blooms.
