Does anyone make a HB with mismatched coils....

Re: Does anyone make a HB with mismatched coils....

The snark factor in this thread is too high. Just have a nice conversation, people.

Common mode rejection ratio. That is what 50/60-cycle hum is: common mode noise.

As to which DiMarzios have different wire gauges, the DCR can give you a hint, but only for the very hot or very weak models.

BTW I hear no noise whatsoever with my mismatched brobucker and burstbuckers.

If you mismatch the two coils drastically using the same wire gauge your CMRR will start to suffer, and it will no longer maximize the hum bucking effect.

Which adds some single coil sound and gives nice tones. I've made some HB hybrids, mostly for the neck slot ('59B coil + '59N coil, A2PB + '59N, etc), and the difference (imbalance) in windings adds treble and thins out the mids. Clears up warm or muddy neck HB's.

For the OP: There are a number of companies that make HB's with unbalanced coils.

A couple of DiMarzio's also have very unbalanced coils (I've used them to make hybrids): Fred and Bluesbucker.

Fred would have both coils with around 5,700 turns on each side. I don't think its unbalanced as it uses different wire gauges.

Why do the specs on their site show a difference of a few hundred turns between the coils?

They used to publish detailed specs including wind count.

A search on this site also confirms they are mismatched. Did you count the turns?

As I've said many times: you should never trust anything published by Gibson, as half of it is wrong and the other half simply not true. ;)

For the record: do you really think Gibson will publish the real recipes of their p'ups, being their designs protected under Intellectual Property Federal Law? That'll make'em openly liable for any case in court, not to mention breach of the Non Disclosure Agreement clause included in the standard deposit form.

I thought that when I started the post by saying "actual turn count on several BBs" was clear enough? What part of that quote you did not understand?

....but NOT like a duncan hybrid where they are wound with different gauges. In other words, both coils are would with the same wire but one is wound lower. Or is that even design that could work? I realize it'll be noisier. I'm asking because i have been thinking of taking one of my dimarzio super D's and unwinding the screw coil from 7k down to 4 or 5k to lower the pickup's output while leaving the slug coil the same so it splits as well as it does now. I love super D's but i'd like less output without affecting the split sound and maybe the pickup would generate some interesting tones like the 59/hybrid does. I just don't know if this is a design that would be faulty given the same gauge on both but i thought i'd ask if there are any winders making something like that so i'd know it could be worth a shot.

I'm not sure how this thread se quickly devolved into an argument, but I have some actual helpful advice to offer: replace you split-coil switch with a volume pot. This allows you to adjust the volume of one coil, which is pretty similar to what you are trying to achieve. I did it on a Super D a few years ago and it works.
The other option is to experiment with lowering the pickup and raising the pole pieces to cut some mids. Both options are a lot easier than trying to unwind one coil, and neither runs the risk of ruining the pickup.
Fwiw, some Super Ds are just mid heavy. They don't all sound exactly the same.
 
Re: Does anyone make a HB with mismatched coils....

I've done that many times including with the SuperD. Not what i'm looking for. And i've adjusted the pickup every way imaginable like i always do. I've done all possible things to these pickups in the 20 something years i have used them and trust me, they are not capable of what i'm trying to get from them as they are.
