Why these settings

Because the Boss GX-100 handles the complete British high-gain preamp modeling and boosting, set your NUX Mighty 20 BT to its cleanest, flattest setting with amp gain low to prevent double-gain mud. The Ibanez Infinity R bridge humbucker matches Carlitos' hot bridge pickup perfectly; the GX-100 mid boost at 7 ensures your riffs cut through without competing with the flute and violin frequencies. For the clean intro arpeggios, bypass the T-SCREAM block and switch the GX-100 amp channel to clean.

PRO TIPMägo de Oz rhythm tracks rely heavily on precise, muted downstrokes synced to double-kick drums, so anchor your right-hand palm firmly against the bridge saddles for maximum percussive chunk on the low E string.
