So I wired up my strat with two ssl-1's and a hot rails in the bridge exactly how it's shown on the duncan schematic. However I get hum in all positions except 4 (neck and middle combo). What's the deal? This isn't the first time a duncan schematic hasn't worked for me.

Also, for SSH with duncans, with either rails or buckers: DOES THE RWRP GO IN THE NECK OR THE MIDDLE? I always get two different answers here, other forums, and even when I call seymour duncan company. This matters because if I need to switch them that means I have to buy new pickups because the leads on the rwrp are not long enough to put it in the neck now.

Any help would be appreciated.
