Since a genuine Gibson Mudbucker seems to be very elusive to find (which kinda surprises me, every man and his dog seem to swap them out of the ES0), but a Korean company makes one that looks the same with pretty much the same specs.
I bought one of these from a Chinese vendor, and I suspect it's a Chinese copy of the Korean copy. There was no label on the back as shown in the picture for the ad. the chord doesn't come through a hole in the back of the pickup like the picture on the add shows, and the output value is supposed to be 29.7K +/- 10%.
There are just a bare earth wire and a hot wire. Am I correct in assuming that the resistance through these two should be 29.7k, or close to? I was getting about 0.5k
