Why these settings

The MG30FX lacks the tube compression and mid-push of a JCM800, so the Joyo Extreme handles the heavy lifting on gain structure. I raised mid +1 over the original JCM800 setting because the MG solid-state voicing is flatter in the midrange. Your ESP's active-hot humbuckers hit harder than Hetfield's passive Flying V, so gain stays at 7 instead of 8 to avoid fizz.

PRO TIPLock your picking hand into strict downstrokes just behind the bridge pickup and palm-mute hard against the saddles — the percussive thump on the low E♭ string defines this riff more than any EQ setting.
