Why these settings

The 10-watt GA-10 practice amp lacks the preamp headroom and mid-shaping to produce Metallica's high-gain thrash tone, so it must stay on the clean channel with low gain (2) to prevent muddy stacking. The Boss MT-2 handles 100% of the distortion and parametric EQ sculpting: Mid Freq set around 4 (targeting ~750Hz) and cut to 3 recreates Flemming Rasmussen's studio V-curve scoop. Using the Guild Surfliner's bridge humbucker wide open delivers the tightest attack without active EMG pickups.

PRO TIPEvery single rhythm note must be strictly downpicked with heavy palm muting clamped right up against the bridge saddles to get the signature punch and percussive attack.
