Question re pickup inductance

[ikay]

I've measured the DCR and inductance of the stock higain pickups in my 2019 Ric 4003S which come out as:

Neck - DCR 11.2k / inductance 4.0H
Bridge - DCR 11.0k / inductance 4.6H

Measurements were made via the output jack with the pickups wired in circuit. I realise they won't be exactly the same as if measured out of circuit but should be close.

I was surprised that the inductance of the bridge pickup was so much higher than the neck. The wind is pretty much the same as the neck so would the difference just be down to the larger magnet used on the bridge pickup?

The bridge pup lacks a bit of high end to my ears and doesn't clank like an 80s/90s Ric. I guess this is due to the current higains being somewhat overwound in comparison with earlier versions.

I know that one way to extend the top end would be to de-wind the bridge coil (say down to 9k) which would reduce the inductance and raise the resonant peak. Would using a smaller bridge magnet (or cutting down the existing one - it's made of a magnetised rubber-type material) be another way of reducing the inductance and extending the top end response?

Thanks for any input.
