Why these settings

Slash tracked this iconic Skyliners ballad cover using neck pickup warmth through his signature mid-heavy Marshall setup. On the Spark 40, select the Plexiglas or British 800 model, bumping mids to 7 while keeping treble and gain around 5 to 7 to prevent digital top-end bite. With your Slash Les Paul's warm Alnico II pickups, rolling the neck tone knob slightly off wide open locks in that flute-like singing lead response. For the acoustic/clean rhythm backing switch to bridge pickup and volume rolled to 5.

PRO TIPSlash's vocal-like tone on this solo relies heavily on picking near the fretboard with the neck pickup while rolling the guitar tone pot down to around 6 or 7 to roll off snap and bring out pure creamy midrange sustain.
