The cabinet-busting drop-C# groove of Disturbed's signature song. Dan Donegan tracked The Sickness through a Mesa/Boogie Triple Rectifier with Johnny K at Groovemaster Studios — a tight, mid-present high-gain rhythm built for syncopation and bounce rather than speed. The eerie siren that opens the track is a DigiTech Whammy pitch-dive. Heavy GHS strings and a controlled low end keep the very low tuning from collapsing into mud.
