Why these settings

Because the owned Boss DS-1 provides the primary clipping, the Mustang LT25 is set to a clean Fender platform with amp gain dialed down to 2 to prevent muddy double-gain. The Harley Benton's Roswell bridge humbucker matches Kurt's DiMarzio Super Distortion well, so the DS-1 tone knob is kept at 4 to tame high-end fizz on the digital clean channel. Clean verse sections: stomp the DS-1 off and engage the chorus pedal.

PRO TIPDig in hard with a medium-heavy pick near the bridge saddles to get the signature harsh, raspy pick attack Kurt generated on the opening riff.
