Notes

Studio recording, In Utero sessions (1993); 2023 Remaster is from these original sessions. Guitar is run into a Tech 21 SansAmp for distortion, then into Electro-Harmonix Polychorus (Filter Matrix mode), then into Fender Quad Reverb. Settings based on YouTube gear breakdown and era-correct interviews.

Difficulty

The riff is rhythmically straightforward but requires tight palm muting, aggressive attack, and precise timing to lock in with the modulated/flanged effect for the signature grunge sound.
