Why these settings

The Twin Reverb is a high-headroom clean platform, so the NUX MG-101's DS-1 distortion block serves as the entire gain source while the amp volume is kept clean at 2. To compensate for the Fender Player Strat's single-coil bridge pickup compared to Cobain's bridge humbucker, the amp's mid control is bumped to 6 and the guitar tone knob is rolled back to 8 to shave off ice-pick treble. Reverb is set to 0 to preserve the dry, punchy rhythm attack of the album mix.

PRO TIPUse heavy downward picking with a thick pick right next to the bridge saddles to capture the aggressive, clattery percussive attack of the main riff.
