Use a thick, analog-style sawtooth wave with a heavy low-pass filter.

Pepper the track with metallic "clinks" and "clangs"—sound effects that mimic Alessi’s shadow-scythe or the sound of an alleyway. 3. The Lead "Nervous" Synth

Don’t make it too clean. Add a bit of bit-crushing or vinyl crackle to give it that "found footage" or "old anime OST" warmth.

Start with just the bassline and a ticking hi-hat. Keep it sparse. Add a distant, echoing "Settler" sound effect to ground it in the JoJo universe.

Use extreme stereo panning. Have the "creepy" synth sounds bounce from the left ear to the right ear to make the listener feel surrounded.

In the original, this is where the chaotic energy peaks. In an instrumental version, replace the vocal samples with a distorted, "stuttering" synth lead that mimics the "Ere-Ere!" rhythm.

Add a "slop" or slight pitch drift. The bassline should feel unstable. Use a "wah" or envelope filter effect to give it that talkative, "rubbery" texture found in the original. 2. The Percussion (80s Industrial)
