All Hathor six string humbuckers are now based on PCB boards.
Four conductor wire can be replaced with a longer one if needed, or replaced with new in case of failure.
5 pin connector can be plugged both ways, pickup will play perfectly, only thing will change is sound phase. It can be helpful when pairing pickups from different producers. If you find out they are out of phase when playing together, there is no need to resolder: just flip connector and that’s all ! All connectors and solder points are gold plated.
My invention is new approach to design of baseplate. How many times you find the threads in mounting legs are drilled, to allow pickup to be screwed directly to guitar body ? It’s possible to repair and make new threads, but why do it, if they can be just replaced ?
ALL metal parts of pickup are grounded. That improves noise to signal ratio. This is very important, especially when high gain overdrive is used.
