Custom Shop SDs, no Custom Shop SDs, and spider cracks

So over time there has been a lot of discussion about CS vs non-CS pups around here. I was looking at my PRS the other day and something struck me and I want to share it.

First....yes you could say I AM beating up on SD because of QC

Second....problems don't get fixed if they're not pointed out

Third....it shows the extra care that CS pups get.

What is a spider crack? It's the little cracks that form around the slug polepieces in pickups making the cracks and slug look like a small "spider". It seems that they develop after 12-24 months of being in a guitar. Now I live in a humid climate and won't discount the possibility of the climate playing a factor.

Ok, so I've had 5 CS Duncans: 1 butyrate 78, 1 injection molded bobbin 78 Trembucker, 1 injection molded bobbin brobucker, and 1 Custom/Distortion Hybrid and 1 strat single. I still have 4 of these , the Brobucker was the only one I decided not to keep, and here is what I've observed.

Over the years as I've bought new AND used SD pickups many have the spider cracks, and I asked someone at SD about it and they said it doesn't affect the pickup's functionality and not to worry about it. Well over time I acquired the CS pickups and I found out that NONE of the humbuckers from the custom shop develop these spider cracks. First I thought it was due to the stiffer injection molded plastic, but then I noticed that wasn't the case because my normal buckers didn't develop cracks. This leads me to believe that SDs non-leesona winders are putting the wrapps on the bobbins too fast or too tight, and eventually the stress makes the bobbin break.

As we all know only the more vintage correct pups are wound on the Leesona due to how slow and labor intensive it is compared to the regular winders. So my question is why can't SD lower the tension on the other winders to keep from developing the spider cracks?

So for any of you comparing the CS products/prices I will tell you that in my opinion the cost is justified in by the superior winding that is done that doesn't have anything to do with the black arts or "mojo".

Luke, from the literally SEVERAL HUNDREDS of Duncan p'ups that landed on my worbench, only very few had the "spider cracks" you're talking about.

I really don't know what to say...
 
Re: Custom Shop SDs, no Custom Shop SDs, and spider cracks

Same here i have only come across maybe 3 used pups i have aquired that had "spider cracks" over the period of 20+ years ?
I have a old JBJ and a DDJ both from 83 and both of these have no cracks at all?
and i dont know if it is up to CS specs which it probably is but my 78 duncan custom SH5 has no cracks either? did duncan start using a diff plastic on the bobbins lately?

The CC and APH2 in my Music Man have them. No real way to fix them, I guess.
 
Re: Custom Shop SDs, no Custom Shop SDs, and spider cracks

Not so sure its the leesona winder thats the difference like your thinking. Out of all the pickups that i have the only one that has the spider cracks is a seth and from what im understanding those are wound on the leesona arent they?

Thanks for the replies fellas.

It's interesting that you guys have the CS/leesona wound pups with spider cracks because that hasn't been my experience.
It's got to be some kind of tension issue that happens.

My old red ink JB doesn't have spider cracks. Maybe this is something that's only crept up in the past 5-10 years?

Hmmmmm...

I wonder whether very tight winding is really the cause of the cracks. I mean the slugs are right inside the bobbins, I bet you can wind as hard as it gets and it won't have anything to do with the cracks on the top.

Maybe it is more of a high-wind thing? That awg43 and awg44 pickups move more and cause stress cracks over time when temperatures change?
 
Re: Custom Shop SDs, no Custom Shop SDs, and spider cracks

i wouldnt be surprised if temperature (change) comes into the equation along with tension
