I've settled on ~7.8K for the neck and ~8.5K for the bridge, coincidently the spec for the Antiquity pickups. I'one thousand after an early '70s classic rock polish, fat, warm sound that does not mud up too easily.
Making some assumptions and not considering player, guitar, etc. what is your preference?

Maybe someone has a guesstimate.

And I would like to know what percent of PAF's in '57-'60 Standards and Customs, in the bridge position, are BELOW 8k ohms.
Maybe someone has a guesstimate.
Yes information technology would be nice if TW59 would post the resistance of the pickups in his guitars that are in the vintage registry. Most of the others have posted the resistance numbers.

Resistance is futile. :wah:rofl
.
A resistance reading does not accurately indicate how PAF's sound in my experience. The warmest, fattest sounding PAF I had was in the bridge position my '59 burst and it read 7.8K. The neck PAF read 8.1K so I swapped them around and gauge what......not as fat and warm. :hmm Its a combination of many things that make em what they are. I've improved the sound of a then so PAF with a magnet swap. They have equally much, if not more than to do with the sound every bit anything else.

Really we get along just fine....no resistance at all. :spabout
The only method I know is to put a cord in the jack, select the pickup and put the ohm meter tips on the plug. If numbers attained that way are "acceptable" I can become a few of those conveniently.
Next thing you know, you guys volition await me to counterbalance them. :rolleyes :jim

Adjacent thing y'all know, you guys will wait me to weigh them. :rolleyes :jim
Could you do that for us? It would be near benign if y'all could weigh the plate, bobbins, magnets, shims, windings, record, slugs, and screws separately. Be sure to cull your favorite pair of PAFs.

But, clearly nigh bridge pups in that group are below 8K in the bridge.

The DC winding resistance constitutes a signal loss....
The pickup is modeled as a voltage source with a serial Resistance and Series Inductance... Winding Capacitance is in parallel to all this....
So yous have a resonant tank circuit, (LCR) ......
The book pot value affects the peaking of this resonance....
For simplicity we will exit the cable effects out of this......
The larger the value of the pot is, then the more bespeak is adult a cross it, up to a point, since it is assymptotic... The larger the winding Resistance is then the more than the point is attenuated across the pot, (insertion loss)....
Now if you were to wind the pickup with magic wire that had no resistance, Super-Conductor, the pickup would work fine and mensurate ZERO ohms when using a ohm-meter.... At present the pickup would be a bit louder, due to no insertion loss... The dilemma is that well-nigh people apply DC resistance every bit a "mensurate" of the number of turns...which is fairly proportional...
The IMPEDANCE measurement of the pick-upwardly is more critical and a amend indicator of what is going on...
The impedance measurement tin can show dissimilar results depending on how "hard" you bulldoze coil when you lot measure it.... It'southward all-time to mensurate the coil at the same electric current information technology produces in normal playing operation...

Tom, that's it. But make sure the volume pots are maxed. Then, yous tin add .i kOhms to your readings to compensate for the pots equally you're non gonna unsolder the PUP wires, are you lot? :wah
I've just recently taken a couple of measurements on some very fine vintage Lesters. Only, believe me or not, I tin't recollect the readings, except that zero spectacular was discovered. Nevertheless, I do retrieve very well what came outta the ol' Marshall speakers when I plugged ane of them in :spabout

Were thos speakers powered by i of your Gladius Amps? :ganz

To be technically acurate....
The DC winding resistance constitutes a signal loss....
The pickup is modeled as a voltage source with a series Resistance and Series Inductance... Winding Capacitance is in parallel to all this....
So you have a resonant tank circuit, (LCR) ......
The book pot value affects the peaking of this resonance....
For simplicity nosotros will leave the cable effects out of this......
The larger the value of the pot is, then the more bespeak is developed a cross it, upwards to a bespeak, since it is assymptotic... The larger the winding Resistance is then the more the betoken is adulterate beyond the pot, (insertion loss)....
Now if you were to current of air the pickup with magic wire that had no resistance, Super-Conductor, the pickup would work fine and measure ZERO ohms when using a ohm-meter.... Now the pickup would exist a scrap louder, due to no insertion loss... The dilemma is that most people employ DC resistance as a "mensurate" of the number of turns...which is adequately proportional...
The IMPEDANCE measurement of the pick-up is more critical and a better indicator of what is going on...
The impedance measurement can show different results depending on how "hard" yous drive coil when you measure it.... It'due south best to measure the whorl at the same current it produces in normal playing operation...Chris

I hear ya, Jim, but I think he's just trying to help...Personally, I merely know it when I hear it (most of us practise...), and it has Nil to do with scientific discipline, physics, etc. Has to do with making MUSIC!
The BEST LP I've ever heard is a refinished '57 GT (not fifty-fifty to gold, LOL), with one unstickered PAF, and one stickered, low 7 resistance, and it just sings! in fact, information technology 's the kind of guitar that just seems to play itself, like a perfectly tuned car that can't make a wrong turn...
How exercise y'all 'splain that?
