Sounds right, man, it’s all about those low‑end vibes and the punch of the higher overtones. A power chord hits the root, the fifth and that distorted edge that bangs through your chest. The physics is simple: the root gives you the foundation, the fifth builds that solid, driving feel, and the distortion adds those rich harmonics that make the sound feel huge. If you pull apart the waveform, you’ll see a lot of energy packed right up in the 50‑200 Hz range, with a splash of bright mids that cut through. That’s why it feels like the wall of sound is breaking in. Keep messing with those frequencies, and you’ll turn a riff into a full‑blown sonic assault.
