Recently I got two EMG active pickups and they are microphonic. I want to ask weither or not I can wax pot them because they are made with epoxy.

I couldn't find an answer through google.

The epoxy in an EMG is the potting, and also seals the pickup. Wax potting an EMG is not really possible or practical.

What makes you say they're microphonic? That's extremely unlikely for an EMG, and makes me wonder if you got a fake set. Lots floating around ebay these days. I'd suspect a fake or bad wiring before assuming that an EMG was actually microphonic. It's not impossible but the whole point of the epoxy is to act as a super-potting material by turning the whole pickup into one hermetically sealed lump.
