Why these settings

Because you are playing single coils on an American Pro II Strat rather than Slash's PAF-style humbuckers, Treble is pulled back to 5 and Bass is bumped to 6 to prevent top-end ice-pick frequencies. Selecting the neck pickup with the Strat tone rolled down to 7 warms up the attack and mimics Slash's signature rounded, violin-like woman tone. For the clean intro verse, toggle your guitar volume down to 5 or switch to Tank-G Clean Amp 1 with subtle chorus enabled.

PRO TIPSlash achieves his signature hollow, singing lead tone by selecting the neck pickup and picking firmly over the neck joint rather than near the bridge, giving single notes maximum low-mid bloom.
