I was thinking about matching pickups in HSS sets. I've always liked how my Air Norton worked with single coils when split and particularly when in parallel. I'm not particularly surprised to see the transfer characteristic of the slug coil is close to that of a single coil.
In other threads, parallel combinations are just being touched on, and next time i have the scratchplate out of this strat or other useful pickups on my desk I'll have a better look, but i'm considering discussions whereby one signal or the other dominated in parallel combinations and I'm wondeirng if the tuning of pickup heights for somewhere near maximum quack when in parallel is in fact balancing voltages into each coil so neither coil dominates?
This is mosly me thinking out loud and a stub for me to post further material up at I investigate.

Are those Strat pickups steel core? The Q looks low.
Quack is associated with the comb filtering between the two pickups, which notches out various harmonics, and so if one pickup dominates over the other, the valleys in the filtering become more shallow, you get closer to the sound of that pickup alone, and so the quack is diminished, in theory. Since adjectives are subjective, some might say that an imbalance favoring the middle pickup produces more quack, especially if you're like me and think that the middle pickup is inherently quack-like.

Alnico V, I think a bit overwound, 8000 and 8300 turns is on the warm side and using shielded coax that's a huge 320pF/metre, but here's a Squire affiniy steel-core from 1999 added to the chart.

dammit! my denoise/smoothing peramter is way off, like 0.2 instead of 0.02.
Corrected plot with the raw data and smoothed overlaid. You'll note that in my usual in-depth analysis there's always a plot for each coil with the raw data and smoothed plots overlaid and then omitted for group comparison plots. I probably need to print smoothing values onto each plot for traceability.
Added an Ibanez Infinity S1 as well.
There's way more Q here, but the cutoff frequency is matching the norton slug coil as before.
And back to my usual plot style
