Here’s an article about “vintage” modification on new guitars. For the record, I am a vintage non-believer. Modern manufacturing methods produce much higher level guitars more consistently than ever. One of the biggest bits of snake oil out there though is vintage tone caps, a fantasy that the author of this article does believe. I couldn’t help but think, “That’s not how low pass filters work!” Aside from that, I did agree with some of the things he has to say here.
