A lateral thinking pickup

[Alabam]

This is one i made after getting fed up with the usual way of mounting pickups on the pickguard.
Its all made up from stuff i had lying around my shed.
I got around 6.20Kohm`s on each coil i wound using 44AWG wire.
I threaded the T shaped pieces to make them height adjustable by hand instead of looking around for a screwdriver, so doing away with the spring setup.
When i check up on humbucker wiring i will try that out.
It sounds good using it at 12.40Kohm.
I`ll put a soundbite on next time i post.
If you don`t push the envelope you wont find whats in it.
Ok lads, arm yourselves with your arrows.

Very cool! To have it work as a humbucker reverse the magnet on each coil.

I'm working on a bass pickup with two coils per string.

Thanks for the tip.

It was just a one-off test pickup, trying to figure out humbucker wiring etc, and it was easy to fit in through the back of my test guitar.
By the way what kind of bobbins do you use on this bass pickup you are making?.
I would like to make some with a thinner core to get more winds but can`t get past these plastic sewing bobbins.

For humbucking wiring, each coil has the opposite magnetic polarity, and then wire them so the finish of one is wired to the finish of the other (or starts, etc.)

I make them from nylon washers and screw insulators:



Depending of what parts you use, you can vary the dimensions quite a bit.

What gauge wire are you using? You might need 43 or 44 AWG to get more winds.

I use 44AWG.
I`m starting to get my head round this humbucker wiring system, not easy.

Thanks for the pic, i must check out on the web those plastic washers and insulators you showed me and see if they suit the dimensions i need.

Here's an easy way to visualize it. Think of two coils both wound in the same direction. If they both have the same magnetic polarity (North up) they are both in phase, but will also pic up hum.

Now reverse the magnet in one coil. They are now out-of-phase in regard to the strings. They will still hum also.

Now reverse the wiring or wind direction on one coil. Now they are back in phase in regards to the strings, but hum that is picked up by both coils will be out-of-phase and cancel out. This is because the noise didn't need the magnets to be induced into the coils.

So your composite signal has the two magnetically reversed signals and flipped them back in phase with each other, while taking common mode noise in each coil and canceling it out.

what about those zcoils

Forgive me for jumping in on this one but... Aren't the pickups on the G&Ls just a couple of single coils that are out of phase with each other but covering different strings and thus not cancelling out each other? Or are they coil and mangnet reversed like a humbucker?

they would usually be different polarity and out of phase so that they can be combined with a regular pup.
