Creating a Humbucker

[Govier966]

I like the idea of p/j basses. Im thinking of making a bass with a regular p pickup and a big block j bass style pickup.

In theory it would work. In practice, I'd suggest reading this topic for more details on how to wire it: http://www.talkbass.com/forum/showthread.php?t=559341

And to answer your question, wired in series the pickups will have double the output, and the 18k output might be too hot to handle.

Works just fine, this is two Jazz pickups superglued together, and wired in series, Output matches the P well, wish I could measure it for you.

I had Curtis Novak build me a custom double Jazz pickup that would split into a traditional single coil.

He told me that two single coils would be too hot, so he does each coil half as hot to add up to a regular output.

I had him do one coil half sized, and the other full sized with a coil tap, so that i could run a full single coil, or two half coils, and the output would stay roughly equal.

If you want to know how hot it will be, just take a regular Jazz bass and put the coils in series instead of parallel.
You obviously won't have the tone, but you will get a feel for the amount of output.
