As the JZ-1 doesn’t have a diagram on the instructions part of the site, I am using the “2 humbuckers, 2 pots, and a three way switch” diagram to wire mine up.

This seems fine so far, but I was wondering if the P90’s are identical, or is one a “neck” and one a “bridge”?

Also, is one of them reverse wound for hum-cancelling when on the middle position?
