Why these settings

The DNAFx AmP20 is a digital modeling unit — select the Plexi/Marshall Super Lead model to match Slash's modded 1959. Your SC-450 has similar humbucker output to the Alnico IIs, so no gain compensation needed. The rolled-back tone knob on the neck pickup is critical for the intro's vocal quality; mids pushed to 8 replicate the Marshall's inherent mid-forward bark that cuts through the mix.

PRO TIPFor the iconic intro riff, pick closer to the neck joint and use your fingertip flesh rather than the pick's edge — this rounds off the attack and enhances that singing, vowel-like sustain Slash gets on the opening phrase.
