Why these settings

The Bosston GA-10 is a basic practice amp with only Gain, Bass, and Treble controls (no mid or presence knobs), so drive switch engaged at gain 7 delivers the raw clipping needed today. To compensate for bright Strat single coils against James Hetfield's thick Invader humbucker, roll the guitar tone knob to 8 and keep bass at 5 so the small speaker does not flub out. Adding a Rat pedal down the road will let you switch the amp clean and capture the authentic Kill 'Em All bite.

PRO TIPAnchor your palm firmly against the bridge saddles and execute aggressive, synchronized downpicks to emulate James Hetfield's tight percussive attack on the main riff.
