Yeah, the way a chip is tucked into the board, the color of the caps, even the routing style—each tells a story about what the designer was aiming for. On a 1978 TB‑303 the flat‑panel layout makes the VCO feel tight, the voltage‑controlled filter sounds like it was meant to be aggressive. For me, spotting those quirks is half the thrill of hunting a vintage unit, because once you see the blueprint, you know whether that beast will spit out smooth wobbles or raw, gut‑rushing acid. If you ever find a synth with a layout that screams “intense” or “airy,” give me a call—I’ll pay extra for that personality.
