Still polysol like the aph1/2, or something else?
i assume the same but ?
I'm sure there is other ways they could tweak the pickups to make them sound different from the APH-1's. Yeah, the poly wire would mean they'd have some things in common, but they could also tweak the winding pattern.Yeah specs don't really say. Polysol has a very distinctive response, so if not still that they would be very different than the APHs, aside from just more turns.

IME, the APH-1 are kinda creamy with some top-end sparkle and some low-mid warmth.
The Slash by comparison is bright, cutting, and kinda lean in the lows.
I'm sure they designed them to have things in common, but to me, they're not just overwound APH-1's.
Not exactly the same. As a former employee I only discuss things that are already disclosed and/or public knowledge, just for factual or educational purposes. So it’s not out of place for me to say that we said it was a different wire when the Slash signature came out. Of course it’s easy to see they’re both poly, but when you use different insulation thickness, thicker insulation puts more space between the turns and delivers some openness qualities that you’d get from a scatter wound coil that also is manipulating the space between turns and layers. I have no knowledge or insight on the 2.0 version though.What they share is the wire type and the response it gives...

I'm the other way around. I prefer A2 pickups in the neck and A5 in the bridge (if we're talking about vintage output pickups).
I like my bridge bridge-y and my neck neck-y. Hard and biting vs. soft and smooth.
A few impulse response screenshots (trimmed in the name of intellectual property but readers should "get the picture" if I say that horizontal scale = time and vertical one = output)...
Hand wound coils, PE insulated, NOT wax potted, with and without cover, vs some generic HB of the same DCR/inductance, poly insulated coils, potted:
Now, a zoom on the impulse response of two unpotted HB's whose coils have been wound with AWG 42 PE insulated wire and with main difference their inner parasitic capacitance... Again, the hand wound one had the fastest and most dynamic response. The machine wound one was slowest and sounded therefore more "compressed".
FWIW (2 other cents).
Interesting. BKP Black Dog is one of my all-time favorites, as-is. Doesn't seem that bright in my LP.
I don't know if your BKP are covered and what is the wiring in your LP but IME, different subjective experiences with the named pickups might come at least partly from that... Covers bring Foucault currents... Wiring in a LP often exhibits a high stray capacitance - going up to more than 1nF if the moisture of wood goes into the cotton insulation of braided wire, according to the lab experiments of the GITEC... Both factors darken the tone but also slower and flatten the attack of hand wound coils, whose scattered layers and absence of potting often (= granted, not always) cause a very low inner capacitance (with the downside that hand winding can also lower the Q factor and affect the response like a tone control permanently lowered of a few steps, but it's another question and can be corrected by pots of a higher resistance or no-load pots, anyway)...
The same coils without covers and associated to a low capacitance wiring might exhibit a "naturally" fast and peaky attack, especially with a magnet favoring that - I've tried once some hand wound Skatterbrane's with short A5's in such conditions and they were just unbearingly bright. Once fitted with "slower" magnets (UOA5), covered and paired with a LP style wiring in another instrument, they lost their edginess but kept their clarity and became very nice to my ears...
That's the kind of reasons why the luthier for whom I've worked, a pickups geek having measured 10 000+ transducers in his carreer, was nevertheless sarcastic with me when I evoked pickups out of context or on the basis of one single factor (weither it was wiring insulation or something else)... there's definitively a challenging complexity of interactions around these "simple" things. The more I learn, the less I've the feeling to know, personally. I'm conscious it leads me to ramble in an unrequested way sometimes. Sorry at least for that... ;-)
I thought it was the RC mag that softened the top end.
I can understand that.Not exclusive of the factors that I evoked (wiring capacitance at least if there are no covers)... Just adds a "magnetic" layer to this complexity that I was mentioning. ;-)
I generally rewire all my LPs with mogami coax, which is much lower (and more predictable) capacitance.
