01Joyo Extreme Metal
Use as primary gain source to simulate the boosted JCM 800 stack. The Joyo Extreme is a high-gain voiced pedal—back off the Dist to avoid fizz and keep it tight like a TS-pushed Marshall
The MG30FX's OD channel lacks the tight low-end and harmonic complexity of a dimed JCM 800, so the Joyo Extreme becomes your primary gain stage—set amp gain to 7 (not max) to avoid double-saturation mud. I pushed mids to 7 because the original tone is mid-forward and the MG tends toward scooped voicing. The ESP's EMG-style hot humbuckers will push harder than Hetfield's passive PAFs, so the pedal's Dist stays at 6 rather than cranked. Reverb at 0—this recording is bone dry.
