I found some slugs of this super stuff that fit exactly into the humbucker bobbin holes so I took out the original slugs,cut them in half,removed the ferro ceramic bar and pushed in,or will push in these 5mm high slugs into the bottom half of the bobbins.What about orientation?(of the magnets,N,S),I'll be using it on a baritone with light bass strings and the D and G(six string high bass)off a guitar and in the middleish bridge position.
All norths towards neck and all souths towards bridge or alternating N,S from the top(as in towards my head,or low string wise)to the bottom(my feets).

Since it's a humbucker, all magnetic norths towards neck and all souths towards the bridge should do it.

Let us know how it turns out.

WolfeMacleod	Actually, the slug side on Humbuckers is North. Adjustable side is South. This is most common, anyways. WOlfe

Thanks for the clearing that up.

I figured that for a humbucker, all you need is same magnet orientation within a bobbin, and one bobbin oriented oppositely from the other...if that makes sense.

[mode=german_scientist]
A quick'n'dirty calculation on that neodymium magnet+steel pole piece setup sez the magnetic field at the string is about 30% higher than a stock Alnico V and the magnetic aperture is about twice as wide.

I'm pretty curious, wondering if the big aperture will make it sound more nasal as well as higher output.

Re: neodymium(write spelling)

Well Doctor,It'll be a wee while before I get around to putting it in the guitar or even another one to try it out as I've got one semi constructed thats going to be humbuckers but I'm kinda busy at the moment in a lazy sorta way.
So when you say nasal are you saying that because the aperture is wide they'll,the magnets,take in wider slice of vibration and so will be harmonically richer and as a result more mud but with more frequency cancelling effects...nasal?

In a word: "sorta."

When you widen yer pickup's magnetic aperture, such as when you switch on both neck and bridge pickups, you get what's called "comb filtering" which generally sounds nasal. You get more output, but there are lots of little dropouts in the spectrum.

It's not a bad thing, you just need to want to use it in a musical way.

Good discussion at:

Scroll down to figure 4 for comb filter part.
