Why these settings

The Mxt Ma-30bt is an acoustic/practice solid-state amplifier with a 2-band EQ (no dedicated mid or presence controls) that cannot produce the Mark IIC+ high-gain saturation required for the Blue Album chorus. To prevent severe low-headroom breakup, keep the amp on clean at gain 2 and run a dedicated distortion pedal into the front. On your semi/full hollowbody, dial treble slightly up to retain articulation and stand back to prevent low-frequency acoustic feedback.

PRO TIPRivers Cuomo down-tuned to Eb standard and dug hard into bridge power chords with consistent, aggressive downstrokes to get that monolithic wall-of-sound crunch.
