01Overdrive (TS / Rat block)
Set as a clean boost in front of the amp model to tighten the low end and add high-mid bite.
02Noise Gate
Clamp preamp hiss between fast galloping palm-mutes.
Kill 'Em All features mid-forward British bite rather than the extreme Mesa V-scoop of later records. Using the GE100 Pro's UK 800/JCM model pushed with a boost block recreates Hetfield's modded Marshall saturation. Keeping bass moderate and mids around 6 ensures the gallop riffs stay punchy and articulate on the MSC10 Pro bridge humbucker. Clean/slow mid-section: roll guitar volume back to 6 or switch OD block off.
