Why these settings

The original abrasive SansAmp-into-Fender sound requires pushing aggressive mid bite without turning to modern low-end rumble. On the Mustang LT25, using the high-gain 'Metal 2000' or high-gain rock voice with the onboard distortion stomp recreates the jagged In Utero saturation. Keep reverb completely off and run the Ibanez bridge ceramic humbucker wide open for direct pick attack.

PRO TIPKurt's dynamic shift relies on aggressive, loose downstrokes and hitting the open lower strings hard during the chorus while letting the notes slightly ring out.
