51 split coil P Bass pickup

On the contrary, you got a ton of excellent info, given by several different experienced professionals that happen to be members, that obviously went way over your head.

Ok. Like what? Give me one example to think about.
Why are you giving info that goes over my head? To prove something?
I know a bit for example repairing or making tube amps, bass playing as a pro, watches...
If someone is asking, I try to be as helpful as I could.
I learned that from people that really know their stuff like late Peter Stevens (WAL basses), Ruokangas guitars, Tom Stenback, Johan Lundgren, Aiken amps, Finnish Watchmaker school teachers...

To my original question I get very, very little information.

FYI.

NOW you can throw your usual temper tantrum.

Here's a Split J pickup with large magnets I made one time.
You might get some Ideas from it.

Another pickup you might try in your bass is a Blade Bucker.
You could use the blade data for a Telecaster Bridge blade pickup.
In my experimenting I liked about everything better than a stacked pickkup, but that's just me.

Ok. Nice clean PU.
Perhaps split works on JB. And of course post '57 P Bass.
I try to get dirty and brutal sounding PU to a Pre '57 Precision Bass. The magnets are big part of that sound (one per string and small diameter).
I've made now two split coils to '51 style P Bass. I found them kind of too nice. But one bass player liked and bought one (7,6 kΩ). The latter with 8,5 kΩ is better.
I've tried some guitar rail humbuckers on my bass. Kind of ok, but too far from original single coil.
The stack is now in, and I found it best up to now.

So what is the exact question?
You're making a split coil?
What can the membership do to help?
This pickup forum is mainly commercial builders, and guys in business don't give away a lot of particulars.
So keep that in mind with your questions!

"So what is the exact question? What can the membership do to help?"
My questions were: "Like to hear your opinions how hot to wind it?" "Now I going to try more turns. What would be max turns ? My first intention is 8-9 kΩ. Is over 10 kΩ too muddy? "

I have got from Antigua and Hemholtz, and perhaps a few others, 99 % of all the useful information. Thanks them all.

I made a split coil already, not what I like.

Stack type PU with two ca. 14 kΩ coils (Seym. Duncan clone) works much better to me.

I understand if someone doesn't like to give information.That is totally ok. But what I don't understand is that why then bother "answer" something off the point. And a style like thinking that the person who is asking is an idiot.

[okabass]

As advised before: If possible measure inductance and forget the rest (apart from magnet size and strength).

Ok. Thank you for the right direction. I have that kind of speculations, that the inductance is one of the most important factors.

[big_teee]

Ok.

"Wire size... which makes a huge difference" "Size" means exactly what? Gauge? Diameter?

ps. I'm gettin tired that certain dismissive style some "answer" here. To my original question I get very, very little information. Good advice is if you don't know the matter, you don't 'have' to nitpick something "wise". It seems that excluding some very informative nice members, some are just hair splitting. That's not what I expected to happen on this forum. Sorry. I'm used to give knowledge, and get knowledge.

Wire size can make a huge difference.
If you're not particular, why are you bothering to custom wind?
Just buy a Joe Blow pickup.
I've said before things that make a big difference.
Bobbin height
magnet strength and type
wire size
Wire insulation thickness
TPL
Turns Count
Inductance
etc.
To name a few.

Good luck, then.

If 10 to 20 % is good for 7ender then it is good for me

Good luck, then.

Today, it is not huge. The 50's and 60's wire, there was a much, much larger tolerance than todays wire. Just the nature of the beast back in those days. It is part of the reason the old pickups were so inconsistent readings wise. Partially the sloppy counters, partially the wide variances in the coil wire. The tolerances were so loose back in those days. some manufacturers that required a tight tolerance would measure samples and remove out of spec wire before it hit the stockroom. A lot of NOS coil wire we find today is NOS because it was ridiculously out of spec. Fender didn't care. They used everything they got.

Ok. Thanks.

There seems to be a tendency to look some point with a microscope, and at the same time some points with a bare eye. The order of magnitude is good to keep in mind. Usually music-electronics 10 % precision is ok.

That's what is presume with the tolerances at that time.
On 7ender amp schematics voltages are ±20 %. Precision resistor was 5 %, normal was 20% carbon comp.. Now normal is 1-2 % metalfilm . One rocket engineer (really) wrote, that in the 50s they had to file the carbon composite resistors to get more precision value.

Variation between different AWG 42 wire can not be very big.

DCR difference?

Apparently you don't think you know. Then tell us.
