01Built-in Chorus (Marshall MG FX section)
Select the onboard Chorus effect on the FX dial for the signature JC-120 stereo shimmer.
02Ibanez TS9 Tube Screamer or High-Gain Distortion
RECOMMENDED — not currently owned; for switching into the heavy machine-gun breakdown.
The MG30GFX lacks a dedicated presence control, so treble is boosted to 7 to replicate the bright chime of James's EMG 60 into a solid-state Roland JC-120. Mids are slightly pulled back to match the pristine, scooped Justice-era clean platform. Machine gun riff switch: switch to the OD-2 channel with gain at 7 and scoop mids to 2.
