Why these settings

The Marshall DSL has an inherent upper-mid push, so scoop the middle control to 4 and back off presence to counteract British bite and mimic the scooped Dumble/Two-Rock clean platform. Keep the Classic Gain channel clean and set the TS9 Drive very low with Level high so it adds harmonic thickness rather than hard clipping. The Strat's position 4 (neck+middle) provides the signature out-of-phase scoop heard across Continuum.

PRO TIPPluck the strings using your bare thumb and index finger rather than a pick; Mayer's percussive, fleshy attack is the primary engine behind the soft transient and blooming low-mid thump of this track.
