Why these settings

The NUX MG-30's Two-Rock model captures the massive headroom and low-mid bloom of the original rig. We cut the mid control to 4 to mimic Mayer's classic Blackface/Two-Rock scoop while pushing bass to 7 for foundational body. Using position 4 (neck+middle single coils) on the Fusion-IV gives the quacky, hollow transient essential to the intro chords.

PRO TIPPlay with the fleshy side of your thumb and index fingers rather than a pick to replicate Mayer's soft attack and dynamic touch sensitivity.
