You can't really shield against magnetic fields unless you want a 100 pound guitar with a big box over the strings. So the usual shielding keeps out the electrical noise, like dimmer buzz, but can't protect you from a nearby mains transformer.

That's where you need some kind of hum-cancelling pickup.

The story behind the J-bass pickups with flipped polarity (aka "out of phase") is kind of interesting. The original early models did have the pickups reverse polarity to each other, which gives you the ability to mix them for a sort of low-cut filter (yes, that's a useful feature for bass guitar sometimes!) and to cancel out hum when needed. My brother still proudly plays an old J-bass with the pickups flipped polarity, and it records like a dream.

One idea might be to take a standard J-bass pickup and take out the magnets and maybe pole pieces. Mount that next to your existing pickup and mix it in with flipped polarity.

Once I figured out that the instructions to adjust your pickups as close to the strings as possible are not the best idea for tone, I LOVE using EMG pickups in my Strat and Tele.

They will still hum if you are too close to the monitor but are pretty quiet otherwise and the low magnetic field corrects the intonation problems that having 3 pickups with strong magnets can cause.

The SV in the middle position of my Strat is quieter than the SA pickups in the front and rear.

Another option is to use humbuckers but wire the two coils in parallel rather than the standard series. This maintains the hum cancelling, but makes them sound more like single coils.

Actually, if you're simply looking to rectify the hum, a few diodes will do it. Diodes with a lower forward voltage (germanium, schottky) might be recommended, because the hum probably isn't strong enough to turn on a silicon diode.

I ended up dropping a DiMarzio stacked single coil in the bridge position of my strat. I usually hate these and prefer Duncans, but the price was right. Then I rewired my pots. Now I have one master volume (normal), one master tone that controls all three pick-ups where stock it only controls two, and my third pot is a three position detented one. Detent one is the bridge pick-up coil tapped for traditional single coil noise, detent two is the stacked pick-up in series, and detent three is the stacked pick-up in parallel. Very versatile! Thanks for all the input guys!

This is a rotary switch?
