Their web site does not describe how they define "power". It ought to be a voltage or better, a squared voltage but the output level of a pick-up is related to the strength of the magnetic field too, so just describing the wire says too little.

I just checked and found that the bridge and neck pick-ups of my Ibanez S470 are 16.4 and 8.4 KOhm respectively, yet I do not perceive a significant difference in output level. Part of this is of course that the amplitude of string vibrations is smaller over the bridge pick-up than closer to the neck. The other part is that I set their height to have just that sort of balance anyway… but they are at roughly the same height. The neck has a ceramic magnet, the bridge AlNiCo 5.

Due to musical differences I've decided I can't work with myself any more.

Maybe someone's finally quoting the Hall effect?! Screwdriver on - screwdriver off. Hooray for Roswell!!!

Normally high impedance more output but no always. I have some epiphone where output of bridge pickup is more high of neck, and other where is little high, but are all different model on my all guitars never have same pickup model with different impedance! The problem are three: 1) all Cst24 and sc450+ have bridge pickup with 16kohm ? 2) if yes why same labeled pickups have different impedance? 3) if no why i have 16kohm and then on two guitars? I ask also to thomann but i don't know if I will have a sensible answer given the complexity of the investigation.

The other part is that I set their height to have just that sort of balance anyway… but they are at roughly the same height. The neck has a ceramic magnet, the bridge AlNiCo 5. Normally high impedance more output but no always. Output is directly related to inductance and magnetic field. Inductance increases with the number of turns, which is the main contributor. Of course, the more turns, the longer the wire and the higher its resistance. The thinner the wire, the higher its resistance too and the more turns can fit in the same bobbin. A bad wire, however, will be more resistant without making more turns, so that can be deceptive, and a weak magnet will undermine everything. So I suppose a strong ceramic magnet can be used with cheaper, more resistant wire. I also suppose a strong magnet is more hi-fi but guitar players want distinctive limitations for their sound, just like they want low-fi, distorting amplifiers. It's all a bit of a mess. I need a picture of a cat playing with a pick-up bobbin now.

Do these higher impedance bridge pick-ups sound strange or different from what you would expect?

That's interesting. It really makes me wonder if something is wrong about the measurement, if the added resistance is coming from something else than the pick-up wire.
But if not, it will be another example of having various parts fitting to make a whole. We might discuss ingredients all day long but it's the dish that matters.
