They're based on info I received from Charlie Chandler who worked on Gary Moores PG LP and actually had the covers off the humbuckers.I also got info from the guy who rewound the damaged neck pickup, Sam Lee,so the neck is wound in reverse like the original and with heavy formvar wire(not magnetically out of phase as often suggested).
Magnets-vintage cut 63.5mm rough cast Alnico II.
Gary Moore has been using the PG Blues in one of his LPs on his most recent tour.
