A few months ago I bought a loooovely ‘64 ES-175. My luthier finished a refret on it yesterday, and I asked him to check the pickups as I was curious. Turns out it has PAFs, which I thought were replaced by Pat Nos around 1962. Serial clearly indicates a 1964 guitar. Pot dates were not checked unfortunately, but all wirings and solderings are original and untouched. Has anyone heard of a 1964 guitar with PAFs?
