TOO much false info on web - post pics and info on pups YOU'VE torn down

Re: TOO much false info on web - post pics and info on pups YOU'VE torn down

I question all research. Some unknown idiot posting a pic and saying "Look at all the magnets!?!?!?!?!" doesn't get a a 1/2 second of my attention.

I'll be sending you the bill for the time it took to read this thread. I want that time added back to my life, or you can pay me at my hourly rate in cash.


As for Ed - he is pissed off at everyone. Whatever...
Will that be professor rate or consultant rate?

Take note that at least some (maybe most, possibly - all?) multimagnet pickups apparently run reverse polarity on the smaller mags... at least according to a few other sources on the web.

Might be worth researching.

The flanking magnets face the same polarity as the one it’s facing. So if that set of poles is south, both the center and flanking magnets have south facing the poles.

So it’s like

N-S || S——N || N-S

Here’s one for you guys. An EMG SA

What matrix are the coils embedded in? Mesh shielding?

I thought forcing like-poles together demagnetized magnets over time. How does this work in the long run?

Well, yes it does. They still have a keeper bar between them, so they are not in full contact of course. Its why p90 mags from 50's and 60's guitars are often quite a bit weaker than when they first were assembled.

But of course if you put them in the other way they cancel and you get pretty much no output.

It does. However, in practice, depending on the magnet, to get a noticeable effect due to degaussing might take about 50 years for A3 mags, probably two hundred years for A5 and maybe a thousand years to never for ceramic.

It happens faster if you have magnets that don't match. A ceramic could probably degauss an A3 in much less than 50 years.

Stock bridge humbucker from a Godin Core. It's a G&B with ceramic mag. Single, thick ceramic magnet. Flanking the magnet on each side are double stacked plastic spacers.

The neck bucker is the same, just not wound quite as hot, although they are both pretty hot (near 11K neck and just over 12K bridge).

The neck was intermittent and I traced it back to a damaged hot wire where it entered the outer jacket of the lead, behind the tape. These were factory terminated as two wire pickups but they are all set up for 4 wire.
The ground is tied to the shield and the series link is tied together under factory heat shrink at the end of the cable so only the bare shield and hot wire were exposed for hookup. They could have easily been wired to split just by cutting off the heat shrink at the end of the cable to get to the extra wires buried there.

I didn't take a photo of the neck pickup but since I had to repair/replace the damaged hot wire, I just went ahead and replaced with vintage braid. I don't and never will coil split these pickups and since the switch and jack has been wired with braided cable, I decided to do the same when replacing the damaged lead for the neck pickup. Then, of course, I had to re-wire the perfectly functioning bridge pickup just so it would match. :D

Taped back up.

A bit of a PITA with the mini pots (Bourns) but all wired back up in the control cavity.

So, why bother messing with a set of cheap, ferrite mag, Asian import, factory pups? Nope, I wouldn't put these in everything I own, but I love these pickups in this guitar. They are different. They really don't do clean very well. But the neck isn't muddy, the bridge doesn't cause ear bleeds and there is an awesome grit and raunch to these pups that does dirty blues and rock really well. They sound frickin awesome with a rangemaster into a Marshall. I love them in this guitar.

...insinuating non-existent Jeff Beck and Van Halen endorsements, ripping off Bill Lawrence . . .

I don't think they were endorsments, per se. Just named after them. They were pups that represented their sound. And he didn't "rip off" BL. Dime came to him and said, "make me one of these." It's a subtle, yet significant, distinction. :)

The magnets are touching steel screws or a keeper. Also most of the time these are ceramic magnets, which are difficult to demagnetize compared to alnico.

But P-90s have two alnicos with the same poles facing the screws.
