Why these settings

The Marshall Code 25 is kept on a neutral, clean vintage British amp model with low preamp gain to avoid muddy double-gain stacking with your owned Mooer Black Secret. The Black Secret in Vintage mode provides the compressed, fuzzy midrange bark of Iommi's cranked Laney and Rangemaster. Because the Squier Strat single-coil is thinner and brighter than Iommi's P90 bridge pickup, bass on the amp is brought up to 6, the guitar tone knob is rolled to 8, and the pedal Filter is kept slightly lower to tame glassiness. (EHX Neo Clone remains bypassed).

PRO TIPPick aggressively close to the bridge with a stiff pick, and hit the palm-muted eighth-note E power chords firmly while using subtle, wide finger vibrato on the 12th-to-14th fret hammer-on accents.
