Hi Guys, a little while back I was reading someone's build diary where they had a great tutorial (almost) on replacing the ceramic magnet in the PBG Humbucker with an Alnico magnet. I've lost the thread and I can't find it anywhere.:mad:
I've got some old PBG humbuckers that I was going to experiment with before my next build....does anyone have a link to that thread? or any others that may be helpful.
Any other mods that I may consider.:confused:
Andy i am going to be putting A5 and A2 in these HB'S i have here, its just a matter of stripping them down then changing out the Ceramic for an Alnico mag, which your probably going to have to charge up.
Ceramic mag is 62mmL 13mmW 5mm H
Just take your time and reverse engineer it, the magnet is held in by wax
I must also make a note that the ceramic magnets in these pickups has a very very low gauss reading.
OK heres what you need, i just started a rip down
Some A5 L 2.444" x W 0.492" H 0.125"
the A5 is thinner than the ceramic but will fit fine.

Thanks heaps Tony....anywhere good to order the Alnicos?
By the way...do you rewind them as well or are the windings ok? I'm only asking as I can't wind, got nothing to do it as yet.
Hi Andy i dont rewind them unless they are broken, although the inductance is 4.6H hich is pretty good, the resistance is is not bad around the 9.8K for a HB, these reading taken after i put the HB back together
That H reading is far more important in determining a pickups tone, output than resistance

Strip the surround of the HB then remove the solder i use my blade rocking back and forwards comes apart in seconds, just dont be too heavy handed
Attachment 9531
Need to break the solder
Attachment 9532
Into it with the blade

Must have in the tool kit

I have an A5 here PM me they arnt too dear, i can flick it at cost.Quote:

Out of the cover, theres some wax in there, they arnt potted, they just run some wax between the cover and the poles, and also underneath where the plate is
Attachment 9537
Ceramic magnet is under the bobbins against the pole pieces, watch you dont stuff that wiring
Attachment 9538
A view from the other end, this is the end i work from
Attachment 9539
Gently pries away the bobbins to expose the Ceramic, i take note of the polarity of the magnet, this one was south facing, i put the new A5 in the same way.

Put your screws back in making sure everything lines up, re-solder the cover and your done, new A5 humbucker

You are an effing legend my friend....
As long as it helps alls good
Great write up tony, you need to do one on wax potting too!
I did one a while back StanQuote:

I can see what you mean about the thinner A5 magnet. I intend to wax pot them (20% bees wax and 85% para) as soon as I've done all 4. However, you you think I should shim the A5 magnet with a bit of plastic or something? or will the wax be enough?
Also do you/can you replace the plastic tape around the coils?
