Why these settings

The EHX Big Muff provides the core singing fuzz, so the Mustang LT40S is set to a clean, high-headroom Fender Twin voice with low gain to prevent muddy double-gain stacking. The Big Muff tone is rolled back slightly to tame the naturally bright top end of a Strat bridge pickup into a digital Fender model. The Mustang LT40S physical panel features only Gain, Bass, Treble, and Master controls, so Mid and Presence are omitted.

PRO TIPUse heavy, slow, wide vibrato with the flesh of your fretting fingers and pick close to the bridge with a sturdy pick to get Gilmour's signature singing sustain and harmonic blooming.
